texts not sending, and have tried previous advice on forum

[RosyT]

I have an iPhone 12 mini, and have recently moved from Vodafone to o2. All of my texts say that they are not sending, but some of them are reaching their destination, but only to one person so far. I don't know what provider they are with. I know that texts to other friends have not got through.

If I send a text to myself then the text does deliver to me quickly but the screen shows the green bar at the top moving across the screen from left to right,  and then it gets stuck when it is just over three quarters of the way across, and then I get the red text saying it has not been delivered.

I have read the previous advice on the forum, and my ios is up to date. I've tried resetting the phone. My settings for network provider are:

APN : idata.o2.co.uk  (PAYG : payandgo.o2.co.uk)

Username : vertigo

Password : password

Visual Voicemail  (PAYG : n/a)

APN : idata.o2.co.uk

Username : vertigo

Password : password

MMS

APN : idata.o2.co.uk (PAYG : payandgo.o2.co.uk)

Username : vertigo

Password : password

MMSC : http://mmsc-ac.mms.o2.co.uk:10021/mmsc 

MMS Proxy : 193.113.200.195:8080

MMS Max Message Size : 2097152

MMS UA Prof URL : leave blank

After each change I have rebooted my phone.

Any help gratefully received as I'll have to cancel this contract if it won't work!

Hi, for the last couple of weeks none of my text messages have been sending. I have unlimited texts so not sure why this is happening 😞 my phone is up to date and I have tried other solutions but nothing is working

Check this guide out for text issues @Jasmine_ 

Guide: Text Message Tips (not sent or received) 

If you work through that and nothing helps then I would suggest getting o2 to check your account.

Your phone may not be able to send outgoing SMS for a variety of reasons. You are aware that you send 100 SMS per day from a pre-pay mobile and that you always have a positive balance.

As a first step, when you exchange your SIM card for a new one, whether it is an upgrade or a replacement for a lost one, outgoing and incoming SMS services will be blocked for 24 hours from the respective operator, thus preventing any misuse of your SIM card in the event of theft.

It is also important that you check how long you have not used your outgoing SMS service as most operators block this service due to no use, so they need to be contacted and unlocked manually.
