Unable to send text messages

[ Edited ]

I have just inserted by new O2 SIM card, topped up with £10, and texted FREE10 to 21500 as per the email. However, the text doesn't send and I get a Not Delivered error (iPhone).

 

Any ideas?

Good point, hadn't tried until now.

 

No, I can't text any numbers, they all fail. I can make calls fine.

Try a reboot and a reset of your network settings.
Your message centre number may be wrong or not updated.

Re: FREE10 to 21500 not working

I've now done that, but still no change. I also went to Settings - General to check for a carrier update; there was one which I updated and then rebooted again, but still no change.

I've tried *#5005*7672# to check the message centre number, as described in the post below, but it Unknown Error.

Just been looking at this:

https://community.o2.co.uk/t5/Pay-As-You-Go/iPhone-8-PAYG-Cannot-Send-SMS-Messages/td-p/1228404/page...

Looks like the same problem, which is a faulty SIM, and means a visit to an O2 store to do a SIM swap. Not a great start.

That does sound most likely.

Re: FREE10 to 21500 not working

Thanks for all the help.

 

SMS messages will now send, having changed absolutely nothing. For some reason it took nearly 24 hours after activating the SIM card for everything to catch up, but now I can send successfuly. However...

 

...when I text FREE10 I get the message "It looks like this offer isn't for you" even though I have 2 emails from O2 telling me it is, and that I shouldn't forget to claim it. Any ideas? Maybe something @EmilieT could help with?

I think it needs to be applied manually now. You can either call customer service yourself or wait until @EmilieT gives them a nudge.

 

Good to hear texts are now sending ok.smiling
