Unlocked Telstra USB 4G (ZTE MF821) 4G USB Modem Review

Today, we get a new 4G LTE USB datacard, the 4G aircard model number is ZTE MF821. The 4G modem is packed well in a box, there is the operator’s logo “Telstra USB 4G” on the front box, and the information is telling user this 4G USB modem. The ZTE MF821 is already unlocked by our group, so users don’t need worry about the lock issue.

 

 

At the side of the box, we can see that LTE Frequency bands that ZTE MF821 could work with. The specification indicates MF821 could support FDD LTE 1800/2600Mhz, but per our information from the manufacturer ZTE, the modem MF821 4G aircard could support band 1, band 3 and band 7(1800/2100/2600MHz), we suppose this band is not activated because the operator Telstra is not providing the LTE band 1 (2100MHz).

 

 

 

And the 3G DC-HSPA+ Tri-band (850/1900/2100) is backward compatible. Under the 4G LTE network, user could enjoy high speed up to 10Mbps. Even on 3G network, ZTE MF821 could reach speed to 42Mbps.

 

 

 

Open the package, we can see the 4G dongle ZTE MF821. There is a logo of “4G” and “T”, which means Telstra 4G. On the side, we can see two small icon of signal; they are two hidden connectors for external antennas. This feature is important for 4G data transmission, and it lets MF821 different from MF820 or MF820T. On the other side, there is no slot.

 

 

 

The USB of ZTE MF821 is rotatable for 180 degree, user could hide the USB in the body of MF821. User need open the back over and find the SIM card slot. On the SIM slot, we can see the model number, IMEI number, place of origin (Made in China) and manufacturer ZTE Corporation. And close to the SIM card slot, there is a slot for MicroSD memory card. The MF821 could support maximum 32GB SD memory card.

 

 

 

Comparing with other ZTE 4G Aircard, such MF880 or MF820D, ZTE MF821 is really very slim, the size of MF821 is as big as a 3G datacard.  So if a user prefer a small size USB dongle, ZTE MF821 is a good option and without any contract. But before purchase, user should concern about the 4G frequency band  compatibility, if you want a 4G Aircard for FDD band 20 (800MHz) or TDD band 38 (2300MHz), or any other bands that are not same as MF821 supporting, you may need check other model and choose the right one. You can check here more 4G Aircard for various LTE frequency bands:   http://www.4gltemall.com/ue-by-spectrum.html

 

 

 

 

 

 

ZTE MF820T TD-LTE Modem VS ZTE MF820D FDD-LTE Modem

Most of ZTE 4G modems looks the same, and the first generation of ZTE 4G Dongles are all using same appearance design, so it becomes much harder to identify them. No wonder what the difference between them is. We open the blog especially for clear out the similar 4G devices and let users know more about the details of the LTE modems they had used.

 

 

ZTE MF820T and ZTE MF820D are two similar 4G LTE sticks for first generation ZTE 4G USB modems. Most of the modems, appearance similar or not, their difference are mainly on the core part, that is the platform chipset, which decides what LTE frequency bands that could support and where they can be used.

 

ZTE MF820T is based on Qualcomm MDM9600 chipset, it could work TD-LTE bands 38 and band 40 (2300/2600MHz). ZTE MF820D is based on Qualcomm MDM9200 chipset, it would support FDD LTE band 3, 7 and 20 (800/1800/2600MHz). Unlike ZTE MF880, they can only work on single TD-LTE network or FDD network, MF880 would support LTE dual-mode (TDD&FDD).

 

 

As the typical features of ZTE first generation 4G USB stick, there is no external antenna connector in the dongle, so the LTE MIMO transmission can’t make true. But there is built-in antenna which is still reliable to connect network in high speed.

 

What’s more, there is no MicroSD card slot available in MF820T and MF820D. We suppose they are not for single user, it’s more like designed for large data in project test or other research terms. However, the 4G aircard may be more reliable when there is no SD card sharing function. According to the experience in 3G modems, SD card usually causes the application of wireless dongle in trouble.

 

 

And we can see the big body of the 4G modem ZTE MF820D and MF820T is not user-friendly. It’s almost twice bigger than ZTE 3G modems. We hope there will be some smarter or slimmer models available in near future, and this will not only need the improvement in the design for inner part, but also the function more powerful.

 

How to Buy 4G Modem between Similar Models?

More and more people are choosing 4G modems as their preferred network in the plan. And more and more 4G dongles are available for various operators all over the world. Then here comes a problem: many customers feel confused by the models and especially two similar models. Customer don’t know what’s the difference, which make s them in trouble deciding which one to buy.

 

 

ZTE MF821 and MF821D are two similar 4G dongles. We will take the two 4G LTE modem as example to explain our topic today. Now if I list them in front of you and let you tell what the difference is. You maybe feel headache…don’t worry; if I were you, I also can’t tell anything, perhaps my answer is they are completely the same.  But actually, they are different, of course, not on the appearance.

 

The key differences for most of the 4G modems are the LTE frequency bands that they could support. Other features are almost the same and not influence the usage. ZTE MF821 could support 4G LTE band 1, band 3 and band 7 (1800/2100/2600MHz). But ZTE MF821D supports band 3, Band 7 and band 20(800/1800/2600MHz).

 

Even though some customer may concern about the connector for external 4G antenna, the network bands should be the first concern because it determines whether a 4G modem would work properly or not. And we could see this feature from the dongle body. The inner part, especially the technical specifications are invisible.

 

 

Getting to know the specification of the 4G LTE modem, user need check the operator’s network bands. If the bands are partially the same as the 4G USB dongle or 4G mobile hotspot, then the operators’ SIM card work with the Wireless devices.  But if you are using a USB modem that is not with contract plan, you must make sure the USB modems are SIM card unlocked.

 

 

Above should be the key matters that influence the usage of a 4G dongle/modem/surfstick/datacard.  If you want to know the details of a 4G USB Modem, welcome to check the list UEs by LTE Frequency bands: http://www.4gltemall.com/ue-by-spectrum.html

 

LTE Dual-mode 4G Modem-ZTE MF880 VS MF825

More and more operators are investing the TD-LTE technology so as to improve the spectrum application efficiency. It seems the TDD technology would become the mainstream for LTE network. But We could also see the dual-mode LTE, that is FDD & TD-LTE combination, is also become popular.

 

 

To make the LTE dual-mode network more efficiency, the UEs must also support FDD and TDD bands simultaneously, and they could auto switch between the two modes. We have found there are many USB dongles, mobile WiFi hotspots and LTE router available for such networks.

 

 

As one of the important vendor for 4G LTE equipments, ZTE had released many models that can support TD-LTE/FDD dual-mode networks. ZTE MF880 and MF825 are such 4G USB dongles.

 

 

 

ZTE MF880 is the first generation 4G modem from ZTE. One of the main features for them is they don’t have the connector for MIMO external antennas. The body of the 4G modem is a little bit bigger than 3G modems. As a 4G dual-mode LTE modem, ZTE MF880 could support 4G FDD band 20 & band 7(800/2600MHz), and TD-LTE band 38 & band 40 (2300/2600MHz). Band 7 and band 20 are two most popular spectrums in European countries and the two TDD bands are the most commonly deployed broadband worldwide, which make ZTE MF880 4G data card one of the most popular 4G dongles.

 

 

ZTE MF825 is the typical model for the second generation of ZTE 4G modems. Based optimization and improve in hardware and firmware, the ZTE is much slimmer then it’s predecessors. And it’s not as big as ZTE MF880, and to make the MIMO transmission come true, two external antenna connectors are available in MF825. Besides the TDD band 38 & 40(2300/2600MHz), ZTE MF825 supports more FDD bands, they are band 20, band 3, band 1 & band 7(800/1800/2100/2600MHz). From the specification, we could know if ZTE MF880 could work in any place, ZTE MF825 would fully replace it.

 

 

 

What’s more, the two 4G dongles ZTE MF880 and MF825 could also work on 3G UMTS/DC-HSPA+ networks (900/2100MHz) and 2G GAM/GPRS networks, and the peak download speed on 3G could reach 42Mbps. So if user is in a location where 4G network is not available, the two ZTE 4G modems would switch to 3G to fulfill the Internet access requirement.

 

 

Someone may ask, if ZTE MF825 could fully replace MF880, then why they both are presented from operators? It’s a good question, actually, the more powerful one device is, and the more expensive it is. ZTE MF825 is more powerful based on its great internal chipset, and it costs more. For some operators, it’s unnecessary for them to use a modem with high price when a cheaper one could meet the requirements. And for some operators, they didn’t provide some of the network spectrums that ZTE MF825 supports.

 

But for users who usually travel overseas or to different countries, it would be better to get ZTE MF825, because it would be more possible for the data card to compatible with the target operators when on a trip.

 

To conclude, the LTE dual-mode 4G modems provide better solution for users to access Internet and travel around. If you want more TD-LTE/FDD USB modem, welcome to visit www.4gltemall.com .

 

ZTE MF28G 4G LTE Router VS ZTE MF28D 4G LTE CPE

As the one of the most important UE device to support 4G LTE networks, 4G Router is on a replaceable position. Many vendors are trying their best to improve the research and development on this field. The Chinese vendor ZTE is also trying to present more telecommunication equipments to share the market.

 

As we can see, just ZTE 4G Modems, ZTE 4G Routers also looks very similar in appearance. Perhaps they just want to save more budgets, just using one appearance design and change the inner core part to make up a new model. So users usually can’t identify which model number of a LTE router, even when they know two model numbers of the router, they don’t know what the difference between them is. ZTE MF28G and MF28D are just on the case.

 

ZTE MF28G and MF28D are the 4G LTE CPE/Router from ZTE, they are for the 4G LTE networks and provide high speed Internet connection.

 

 

Appearance

 

As we said, they are using same appearance design, from the outside, we can’t tell from them. There are almost same indicators on the front screen, on the back, there are 4 RJ45 Ethernet cable ports, 2 RJ11 connector for analog telephone and one USB 2.0 interface for host file sharing.  And beside is the plug port for power supply.

 

 

Network Frequency Bands

 

 

The frequency bands supported should be the key difference between the two 4G Routers. ZTE MF28D router is a FDD-LTE router, which support 4G FDD band 1, band 3, band 7 and band 20 (800/1800/2100/2600MHz). And 3G DC-HSPA+/UMTS networks (900/1200MHz) are backward compatible.

 

 

ZTE MF28G LTE CPE is a FDD/TD-LTE dual-mode CPE router. MF28G Router could support FDD band 7 band 20(800/2600MHz), and TD-LTE band 38 & band 40 (2300/2600MHz). Similarly, ZTE MF28G LTE router also could support 3G networks as backup.

 

 

Connection Speed and User Support

 

In good network environment, the peak download speed of ZTE MF28D could reach 100Mbps and upload speed to 50Mbps when work on FDD networks. The speed ZTE MF28G varies depending on the network mode. When working on TDD mode, MF28G could allow maximum download speed up to 68Mbps and upload speed up to 17Mbps. However, if working on FDD LTE networks, the downlink could reach 100Mbps and uplink could reach 50Mbps.

 

 

Of course, the speeds above for data rate speed are theoretical and can make true only in preface situation. In real life, the speeds may not as faster as expected, but it’s still amazing and much faster than 3G speed.

 

ZTE MF28G and MF28D could both allow up to 32 users to get connected and surf. So they are good for SOHO, home and small office. The USB interface is help group users to share the files via host Memory.

Difference Between ZTE MF910 and ZTE MF91D 4G LTE Router

Just like ZTE 4G LTE USB modems, ZTE 4G LTE mobile Hotspot looks the same in appearance, but there are some difference between these models. ZTE MF910 and MF91D are two 4G mobile pocket router that looks the same.

 

 

 

Today, we will have a Review of the two similar 4G Pocket WiFi Router. As we know, the ZTE MF91D 4G hotspot has already been presented to public for operators in many countries. It seems ZTE MF910 WiFi hotspot seems not as popular as MF91D right now. But after we review the two MIFIs, you may change this idea.

Appearance

 

As we can see, the two mobile hotspots look very similar, we suppose the manufacturer ZTE use the same design appearance for MF910 and MF91D. There is only one button on the front of device, below the screen. There are WPS button, MicroSD card slot and external antenna connector at the side of the body. And one more USB interface for battery charge.

 

The SIM card slot is in the inner part of the body, user must open the back cover and remove the battery to insert SIM card.

 

 

 

 

UE category and Link Speed

 

 

ZTE MF910 and MF91D are both LTE category 3 mobile router, as the typical feature of Cat 3, the mobile 4G router could support maximum download speed up to 100Mbps, and the peak download speed could reach 50Mbps.

 

What’s more, the 3G UMTS and 2G GSM/GPRS networks are backward. When working on 3G DC-HSPA+ network, the peak speed could reach 42Mbps. So when user goes to somewhere 4G network is not available, the 4G MiFi could auto switch and work on 3G network in high speed.

 

 

Networks Bands

 

This should be the core difference between MF910 an MF91D. Because this decides where they could work and which operator they would support. The ZTE MF91D could support 4G LTE Band 8, Band 3 and Band 7 (900/1800/2600MHz) while ZTE MF91D would support the three bands and Band 20(800MHz). With this specification, they both could roam in most European countries. But in some specific areas, ZTE MF91D may be unable to work on 4g Network. For example, if user uses the MF91D in remote area far from downtown where the 4G band 20 is deployed, it may not connect to 4G and switch to 3G network.

 

 

It may not occur on ZTE MF910 because it supports the most popular three LTE bands in Europe areas. So unlock ZTE MF910 could fully replace MF91D. Someone may ask, then why the two models exist simultaneously? It’s a good question, usually, the more bands a UE decide could support, the more expensive it is. So ZTE MF91D is in lower price than MF910. And some operator didn’t adopt the LTE band 20, it’s unnecessary for them to order a device with this band supported.

 

 

By the way, almost all the LTE mobile WiFi Hotspot could support up to 10 WiFi users to access Internet and surf, including the ZTE MF910 and MF91D.

 

 

 

In conclusion, ZTE MF910 4G hotspot is more powerful than MF91D, but user could buy budget MF91D per the actual situation. If you want know more 4G mobile hotspots, welcome to land www.4gltemall.com .

 

 

 

 

Difference Between ZTE MF93E and ZTE MF91D 4G LTE Mobile Hotspot Router

Following the commonly deployment of 4G LTE network worldwide, more and more 4G terminals are demanded by the operators. As one of the important vendors, ZTE had gained many business plans from the operators and its wireless gadgets are also very popular. ZTE MF93E and ZTE MF91D 4G LTE mobile hotspot are two models for 4G LTE networks.

 

 

Sometimes, most customers may know the model number of the UEs. But they don’t know whether the 4G modems or 4G routers would work with the providers in their countries. Today, we will have a review of the two models ZTE MF93E and ZTE MF91D.

 

Network Frequency Band

 

ZTE MF91D 4G Hotspot is earlier available in same countries, it’s mainly European 4G networks. MF91D Hotspot supports 4G FDD band 7, band 8 and band 3 (900/1800/2600MHz); they are the most popular three spectrum band in European area. And the 3G UMTS & 2G networks are backward compatible.

 

 

 

 

 

 

ZTE MF93E 4G Mobile Router is a LTE dual-mode (TDD & FDD) WiFi Hotspot. It supports TD-LTE band 3 & band 7 (1800/2600MHz) and FDD bands 38 & band 40 (2300/2600MHz). Based on this specification, MF93E hotspot router is more suitable for the 4G networks in Asia and Middle East areas, such as Hong Kong, Saudi Arabia, Kuwait, China etc.. Just like MF91D, ZTE MF93E dual-mode TDD/FDD hotspot could also works on 3G UMTS 900/2100MHz and 2G GSM/GPRS networks.

 

 

Appearance

 

The appearance of ZTE MF93E and MF91D looks not the same. MF93E is in the design of horizontal, but MF91D is in vertical design. To make the device more user-friendly, the both have only one button in the front. And there is OLED screen to indicate the important information, including network status, operator, WiFi connectors, battery life and data statistics. The batteries in the body are removable and re-chargeable.

 

 

 

Link Speed and Connectors Support

 

 

ZTE MF91D 4G Pocket Router could reach peak download speed up to 100Mbps and upload speed to 50Mbps on 4G LTE FDD network. It could allow up to 10 users access Internet simultaneous. ZTE MF93E has the same functions like MF91D when it’s on FDD mode, however, when working on TD-LTE network, MF93E could support maximum download speed up to 68Mbps and 17Mbps for upload.

 

 

 

Above are the important features of the 4G Pocket WiFi that matters the user experience, if you want to buy unlocked ZTE MF93E or MF91D, welcome to land www.4gltemall.com .

ZTE MF28B Rogers LTE Rocket Hub VS ZTE MF28G 4G LTE Router

As one of the main 4G LTE telecommunication equipment vendor, ZTE has presented many 4G LTE router to public, and most of them are already for operators’ contract plan. Unlike Huawei B593 4G LTE CPE many modification models, each of ZTE 4G LTE routers has specific modem name, even though they look almost same in appearance.

 

 

 

ZTE 4G LTE routers are designed in same appearance model, but they are not completely the same in some aspects.  Today, we will have a review of the difference between ZTE MF28B and MF28G 4G LTE Router.

 

 

Network Bands

 

Most of the routers with appearance differ on the network bands. They are for different operators. ZTE MF28B Router is for Canadian operator Rogers, and it’s also called Rogers LTE Rocket Hub, but MF28B Hub could support single LTE band 7 (2600MHz), 3G HSPA (850/1900MHz) network is backward. As we can, it mainly for 3G network in North America.

 

 

ZTE MF28G LTE Router is more powerful, it supports LTE dual-mode (TDD & FDD), it could support 4G TDD band 38 & band 40 (2300/2600MHz) and FDD band 7 & band 20 (800/2600). And ZTE MF28G supports 3G UMTS 900/2100MHz. ZTE MF880 4G LTE USB dongle could support these bands.

 

So unlocked ZTE MF28G could work with more 4G operators and in some countries, MF28G could replace MF28B.

 

 

Data Rate Speed

 

 

ZTE MF28B and MF28G could both reach peak downlink speed up to 100Mbps and uplink speed to 50Mbps on 4G FDD network. Simultaneously, MF28G could reach peak downlink up to 68Mbps and uplink speed to 17Mbps when working on TDD networks.

 

 

Interfaces

 

 

There are some adjustments in the bodies of the two ZTE LTE routers. MF28B has only 4 Ethernet ports (RJ45) while MF28G has 4 Ethernet. Ports, 2 RJ11 ports for telephone, and one USB 2.0 host port. So MF28G could support telephone and SD files sharing, but MF28B cannot.

 

 

Logo

 

 

Sometimes, the logo on the router may vary according to operators. And the firmware may also be customized for operators. As we can see, the Rogers LTE Hub ZTE MF28B has Rogers’s logo on it and the forms are version is also with Rogers logo.

 

 

 

Other features of the routers are almost the same, to conclude, Unlocked ZTE MF28G is powerful when roaming globally. In certain countries, MF28B may be reliable on 3G networks.

 

What’s the difference between HUAWEI B593s-22 and B593u-12?

Here now, we get to know there is a new model available now for HUAWEI 4G LTE CPE Router B593, the model number is HUAWEI B593s-22, its appearance is almost same as other HUAWEI B593 sub-models, such as HUAWEI B593s-82, B593u-12, B593s-58, B593s-58b, but there is really some difference between these models.

Let us talk first the difference between HUAWEI B593u-12 and B593s-22:

From the above image, we could see that HUAWEI B593s-22 supports more 4G LTE bands, not only support FDD Band 800/900/1800/2100/2600MHz, but also TDD 2600MHz, while B593u-12 supports only FDD bands.

Secondly, the downlink speed of HUAWEI B593s-22 could reach up to 150Mbps while B593u-12 supports 100Mbps. So HUAWEI B593s-22 is actually a LTE Category 4 CPE Router, like HUAWEI E5172 4G LTE CPE.

Thirdly, the interface in the device is different, HUAWEI B593s-22 has only one USB interface in the device while B593u-12 has two. other features are the same. Other B593 Router sub-models have same appearance as B593u-12, just frequency bands are different.

So HUAWEI B593s-22 is a 4G LTE Category 4 Router even with same appearance like B593 other models. It’s a dual-mode LTE Router for TDD/FDD modes.
