The device is certainly not bad, but I do not recommend it. For almost the same money, itโs better to take Huawei B535-232, which has antennas in the kit, and the firmware works perfectly, you can also use Huawei software together, which does not accept locked B315S. And outwardly, the B535 is much nicer and thinner than the B315S. B535 seems to be somewhat pot-bellied. Regarding non-delivery with a standard SIM card - earlier the SIM card was in the modem, where either mini or nano sim are usually used. In my case, I had to look for an adapter from nano sim to a regular one.
