Problems with Celular Data after update to 7.1.1

Shmuel

We have 2 UMI Z smartphones.
I'm having problems with 3G and 4G after updating to 7.1.1 on both devices.
YouTube for example can't connect to internet although the signal strength seems very good.
Has anyone else encountered such a problem???

Thank You for any halp

I downgrade one of our UMI Z to Android 6 (20170412_g15v97_kw_u8_4m) and the problem of very slow communication in 3G and 4G continues. I put  the sim in my old smartphone and the celular data there is very fast.
I dont know what to do.
