Hello!

Since a few days I can’t receive any MMS on my refurbished S7 edge. I just checked my APN on my provider’s site

My mobile data connexion is failing randomly. Sometimes rebooting the phone fixes the issue or switching plane mode on and off… but this is really random

Any advice ?

Can you test the sim in another device to rule that out, sometimes the sim card itself can fail
