old sim card in new phone

frogbottler

Query on behalf of a friend on a very, very old O2 payg deal with unlimited free texts and £10 top up only when credit expires -usually every 6 months. Wish I had the same deal!! The phone is used primarily to send txts including frequent texts to Australia.

The keys on her phone are sticking so she bought a new phone (from carphonewarehouse)

Put existing O2 sim card in new phone sent several txts to Aus - phone showed "txt sent" screen but none of them have been received.
Put sim back in old phone and the texts to Aus are received.

I suggested the new phone was blocking sms to Aus but she'd been told it wasn't. She took it back to carfone who couldn't figure out why it was happening but did give her a full refund. Phew.

Any ideas why the texts didn't arrive?
If she buys another new phone is the problem likely to recur? If so is there a work around inknown to carfonewarehouse?

She's loathe to switch tariffs for obvious reasons:rotfl:

Be grateful for any help/advice.

Her acc may not have international call/texting enabled. A quick call to O2 would sort that.
I have known some really old sims to play up using newer features (not that texting is one !).

The only thing I can think of it that the text message settings on the old and new phones are different. If this friend gets another phone, try comparing the settings in the old phone compared to the new one. Look at things like the message centre server number, also just try ringing O2 to see if international roaming's been activated - though I wouldn't have thought that would make a difference when texting from the UK.

Sorry, completely miss read the first time through. Ignore my repay.
The info above is mostly the right answer, if its a sim free phone it won't have the network setting for O2 in it...
