sim-only to sim-only upgrade through My o2 app

[Anonymous]

Hi,

Has anyone had experience of upgrading through the My o2 app?

I would like to change from one sim-only tariff to another sim-only tariff. Would the changes happen automatically if I did this (i.e. would it apply to the sim card I already have in my phone and to my current phone number - I wouldn't want to receieve a different sim and/or a different number)?

Thanks

Hi @Anonymous

I am on a Sim only contract and whilst I am sure it could be done online I chose to ring CS to make sure I got everything I wanted and there was no error. My initial simo ran out in January 16 and I contacted CS and started my new sim only contract . http://www.o2.co.uk/contactus

Edited to add ..I did receive a new sim card but was told by cs to ignore it and continue with the one I had currently. It took 10 minutes. Email came in immediately and I was good to go...

The tariff change will take effect at your next billing date and it changes on the o2 system, so you just carry on with your sim as normal.
Nothing will change at your end.
The date it will become effective will be shown when you select the tariff change in the app or in your MyO2 from a PC.

I found it better to call customer service and chose the option for leaving. I got a £4.00 discount for 'staying' with O2 on a sim only.
