No internet access via mobile phone - is this a normal problem with all networks and phones

[#1]

I have watched with amazement the number of posts related to no internet access from mobile phones and, as I don't have any experience with this, I would ask whether this is a normal problem with all providers or something specific to Plusnet

I have several children who have mobiles on a number of networks and they haven't reported a problem where there is sufficient signal strength

Since i got the simcard i have no data yesterday they told ee fixed the problem but still no data and now they are saying it is fixing today tomorrow everything ll be ok. But i think only plusnet problem coz ee/voda or virgin has no problem.if tou never had data probably your simcard itself or apn setting.my next step change the sim card.
p.s.and it is always loosing signal too.

Jim , I have never had problems with my O2 3g/ 4g Internet , so it must be specific to PN

Plusnets own website shows they use ee so why is O2 being mentioned all the time?
