network problem in galaxy M31

[megamonster]

Iam using Vodafone sim in mobile..this is the fastest 4G network in my area..after starts to use this mobile, iam facing network problem very badly while others getting good network speed in the same network ..i tested my sim with other mobile and internet is very fast in my sim.The problem is not only in mobile data speed,but also in WiFi internet speed..while othe mobile the wifi is getting with full speed.. But my mobile (m31) is not Accessing that much internet speed.. Even I'd reset my phone phone twice...but no use of it.

We are not cheated...we are fools who don't read specs
this phone supports LTE but no 4g

The same here.

last weeks something crazy with network: it turns very-very often into H+, and until restart (or enable/-disable airplane mode) it becames in H+...

Dear Samsung Team, please help, or you'll lost customers!!!

also you are! didn't you see on the specs that this phone doesn't have 2100Mhz which Vodafone sim values most on that band😑
