Good afternoon. I want to share the experience of using the USB modem I bought. In short - a good modem.
Having bought an Android tablet without a 3g module, II thought to buy a 3G modem that would work without problems with it and with a PC. The work had the prospect of traveling and the modem was needed in any case, and given that no one canceled trips abroad, he decided to take it without being tied to the operator. On Ali I came across this model with a price of about 500-600 rubles and also with a microSD slot, I decided to take it.

A little bit about the chip
info c 3dnews
Chipset MSM6280 is the seconda complete HSDPA solution that supports bandwidth up to 7.2 Mbps with QoS support, which makes it possible to deploy advanced services related to the transfer of data and multimedia information. In terms of contacts, radio parts and API, the chipset is compatible with the first implementation of the company’s HSDPA-compatible solution, the MSM6275 chipset, which makes it easier for manufacturers to use the new version. The MSM6280, in conjunction with proprietary single-chip receivers and transmitters, provide a more integrated and cost-effective configuration. The chipset supports WCDMA (UMTS) / HSDPA and GSM / GPRS / EDGE (EGPRS) standards, and also provides many multimedia functions, including the ability to work with video, audio, images and three-dimensional graphics. The chipset supports the Launchpad integrated application suite, which provides advanced multimedia functions, connectivity, location, the user interface and the ability to work with removable media, as well as the proprietary BREW service platform. The MSM6280 is also compatible with the Java environment; Java 2 Micro Edition (J2ME) can be "integrated" directly into the chipset, as an extension of the BREW client.
Came packed in a yellow bag with a little bubble and then a container with a modem.
Outwardly, nothing special. The LED lights up blue when working, red when the device boots. MicroSD slot under the SIM card slot.
Everything works fine with the tablet (with the mapBeeline), just plug in through OTG and restart. No photo, because The tablet has long been gone. There were no problems with working on a PC either; when connected, we see
PC sees a flash drive
next we put the program and
when polling a modem in windows we see
I use the modem for about a year, everything is fine,It is heated medium. Communication holds no worse than the rest. It’s bad that the connector is not swivel, and laptops are not very convenient, but swivels die faster (for 2 comrades, they died in the places of turns).
Half a year ago, my wife washed in a typewriter with a jacket, took it apart, dried it - everything works.
A bit of inside
Conclusion The modem is good. I survived the washing and there are no problems with it, if you look closely, then inside there is a connector for an external antenna, if anyone needs it. I tried to flash to change the menu, but it did not work. In general, he obviously worked his money. If anyone has any questions, then ask in the comments, otherwise I don’t know how USB modems test.
Do not forget about
