[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.

Go to setting ->reset ->reset network setting then switch off and on the mobile. I tried this

im at tesco and had same issues for last 2 weeks. tried this and its flying

settings_connections_mobile networks_acces point names then tap on your carrier and on the next window change autentification type_ from none to POP and CHAP then chose ipv4/ipv6 both APN CONTROL and APN roaming then tick in BEARER every each you have in the list except unspecified

i would attach some pics but no option for that

try this . should sort out the problem

good luck
