Sim not working properly

[BrianOC7382]

My internet connection has been terrible since coming back from abroad. It also doesn’t connect when I’m abroad. I’ve tried all many of the recommendations. Maybe I need a new sim?

Maybe try this - the bit titled "Returned Home?":

And make sure that your APN settings are configured correctly:

If that didn't help then maybe try a replacement SIM too see if that helps at all:

With regard to roaming...

What exactly is/isn't working? 

Connection to a local network - i.e. signal bars? 

Incoming/outgoing calls? 

Incoming/outgoing texts? 

Mobile data? 

As ever, the usual general advice applies in relation to 48 roaming...

Unfortunately many people still seem to have problems with roaming abroad on 48 for some reason.

(On the other hand all the people who have no problems don't post to report their positive experiences!)

If your SIM predates January 2023 then a replacement may mitigate or eliminate roaming problems:

It may be worthwhile reviewing these threads in case any of the suggestions help to avoid roaming problems:

If mobile data doesn't work while roaming abroad in countries where it's supported then check that your APN settings are configured correctly:

• https://community.48.ie/t5/The-Knowledge-Base/Data-APN-Settings-i-e-Internet-amp-MMS-Settings/ta-p/5...

In some countries an active membership plan and cash credit to pay for mobile data usage are required.

If you have returned to Ireland from roaming abroad and are having problems using the 48 network/calls/texts/mobile data then see this key post, in particular the section titled "Returned Home?":

If you still have problems then you'll probably need to contact 48 support for further assistance.
