iPhone 8 PAYG Cannot Send SMS Messages?

[gmarkj]

Not sure - I have an Android so it is different.
According to the link below, from your dialling screen dial *#5005*7672# and press call.
If it shows +447802000332 then it should be correct.
If it shows something else, then you dial the number you tried originally (**5005*7672*+447802000332#).
Did you transfer your number from another network, or move from pay monthly to pay as you go?

Just checked that guide on my PC @gmarkj 

Good find. (never knew it existed!!)

If you have wifi calling enabled in My O2 you may get an error message. Disabling it will allow you to dial in those codes.

Can you enable wifi calling on payg @jonsie? Thought it was pay monthly only (but willing to be corrected)....

Nice to see all the troubleshooting here guys.  @DaveC  Sorry to hear you've been having trouble with this - have you made any progress since you last posted? Any luck with customer service?

Hi, I was on an online chat with O2 last night for 1-hour 20 mins. The first level of O2 support passed me up to the 2nd level. The 2nd level of support said I would need to speak with the 3rd level of support who was not available until 8 am. The problem I have is that it's my wife’s phone that has the issue and I do not have her phone to hand for testing purposes. It seems I’m getting nowhere so I might have to consider switching.

Hey @DaveC , sorry to hear that, sounds frustrating.  I'm not sure how much more could be done if you don't have the phone at hand, but I'm happy to check with our Gurus to see if they can help further in any way. I'll drop you a Private Message here on the forum shortly to get a few additional details.

My wife called into an O2 shop and carried out a SIM swap. This has now resolved the SMS text issue and she can send text messages to android devices. Thanks to everyone for your assistance. David :-)
