iPlay 8T in very weak network

Hello!

I’ve bought 8T at aliexpress from official store. The tablet is very nice. It works perfectly and fastly. But i have troubles in our russian networking. In our district very weak signal of H+ (HSPA+ or HSPAP) and beautiful signal of H or 3G (HSPA). I’ve try to change signal from EngineerMode menu (*#*#4636#*#* and *#*#83781#*#*), but there are only EDGE and HSPAP, not HSPA. Can you know, may be there is some way to fix network to HSPA only? Or may be there is settings for change sensitivity of network chip?

Thanks.

All ok. I’ve changed sim card to other operator and the tablet run at full speed now on 4G without troubles. Thanks!
