I have been away for a few weeks and didn't renew my subscription before it expired. Since then, I've used the Top Up function to buy €20 credit and used €10 of that to subscribe for Guido. All of this is "logged" on the 48 website. However, when I try making a call (or, indeed, receiving a call), I get a message saying "Not registered on network." I've tried going onto the Search Networks function of my Samsung S3 and have not found the 48 network. I also tried O2, but was told that the SIM could not connect to that network. Any help would be much apprecaited.
You might need to contact 48 support about this.
Any chance it's an iPhone?
If so you could try syncing with iTunes and see if that helps.
My recollection is that sometimes (always?) when you roam abroad with an iPhone that was working on 48 then you need to reactivate it on the network by syncing with iTunes when you get back. If this is the case you will also need at least 25c in cash credit on your account to cover the cost of the UK SMS that this process may send.
Hope this helps.
I suspect that you're being too kind when yo suggest that it can easily happen! However, disaster averted. Again, many thanks.
