Can't top up

[Anonymous]

I bought an O2 PAYG sim from Sainsbury. Have not been able to top up from the first instant. Talked to live chat but to no avail. They said they will forward to support team. That was 12 hours ago! Still no help!

As it's not a widely reported issue I can only assume you have a faulty sim or it's not activating correctly - either way if you call into an O2 shop they will give you a free replacement, so no need to loose your quid

It sounds like the sim has maybe expired, underneath the barcode on the back of the pack it should say "Activate by mm/yyyy".

exact same issue here. Support chat just says top up with voucher.

If it is "exactly the same here" then you are advised to go to an o2 shop and swap you sim assuming the number is still active?

Same here 7 different sims ALL in date 3 different bank cards and 3 different phones used.

rubbish service.

Try checking if your postcode registered with your bank is the same you are entering when topping up. Having said that, o2's address data base is often needing updating. It's usually a mismatch of postcard or there are too many cards already used to top up.
