I bought YOTA for a SIM card, native YOTA modems constantly lose contact with the tower . a break for many, I thought it was a telecom operator, but after purchasing this router, YOTA is again in the favorites of Internet operators . disconnection is a very rare occurrence, stable operation of the device, so you even forget that there is a router . it does not make itself felt. I recommend to buy. By the way, almost all cell towers in 2022 are equipped either by Ericsson or more often by Huawei, it is no coincidence that Huawei mobile phones work better than others in terms of communication quality. The router is good.
