I've just signed up for new service provider and ported my old number to the new sim. The number got transfered fine and I can make calls but there is no data activated. I can turn on the wifi but no data connection. It's been six days without any data.
My phone is HTC One A9.
I've tried following so far....
Turning phone on and off (lol, multiple times).
Settings > Bachup & Reset > Network setting reset.
Remowing the sim and giving it a clean and replacing it.
@magicshaw You'll need to speak to customer service. https://www.o2.co.uk/contactus We always suggest calling rather than using Live Chat.
It may be that you have the in correct phone settings or data bolt on. Try texting ACTIVE to 2020 and save the settings. Reboot the phone after.
@magicshaw As I suggested earlier, call customer service and they will talk you through it, or better yet, if you have an O2 store nearby, call in and they should be able to help you with the setup.

This is getting frustrating and complicated than I first thought. I'm not a techy guy.
@magicshawHave a look at these data settings for Android phones. If they are wrong you can change them manually https://www.teamknowhow.com/discover/discover/o2-apn-settings#Android%20APN%20settings%20for%20O2
If they are the same, then you need to speak to customer services from the link given above
Just gave CS a call who transfered me to a "guru" who walked me thru a mannual selling which I had tried three times before.
Fair to say it didn't work and I'm still without data connection 
Have any of these so called "gurus" actually checked your account settings on the O2 system?
If you have the correct settings here and the apn iset to active then maybe it's a faulty sim card. I would suggest tat you get it replaced instore. If possible, can you try the sim in another phone?
