Is it necessary to buy a USB modem from a specific carrier?

Question

Computer networks

The operator offers to buy a USB modem of its brand for use. Is it mandatory, or can I use any other?

Answer 1

No, nothing is required. there are standards for cellular communication and data transmission, from which there is no escape.
Most branded modems are the same China, only blocked on one ops.
This is beneficial for Opsos, because he sells them at a discount, plus he buys them in tons at once for the entire EEC-USSR, which also gives additional reductions in price.
Unlocking usually requires straight arms inserted into the right place.

Answer 2

Are you worried about whether you need to buy a high-fee modem from a megaphone or a high-way modem from mts? =D

Answer 3

you can use any other. not locked by the operator.
if you basically need a connection, and speed is not important.
but sometimes - you need to choose the operator's modem.
Let's say LTE if you want at maximum speed with support for all Bands, then it's better to take a proprietary one from the operator.
simply for the reason that a similar modern non-operator one will cost MORE .
the operator subsidizes modems.
if you do not need the maximum theoretically achievable speed from your operator in your area, take an inexpensive third-party modem.

Answer 4

Not necessary. Tyrnet is full of recommendations for unlocking and online calculators for calculating unlock codes. I have a Huawei whistle lying around in my desk, from MTS, with a SIM card of Teletubbies - it was also locked ...

Answer 5

You can of course use any other one, but you will need a SIM card for it
