I have a CPW o2 contract and just tried calling 21202 and was told (by a rather stern, patronizing toned lady) that the no is not recognized. Is 21202 a voice no or a no to send an sms request ?
TIA..
I can confirm that nixforfun is right. The procedure on O2 Direct is that you send a blank text to 21202, and get your balance and remaining allowances sent back to you almost immediately by return text(s). It works extremely well. If you go to the O2 website and input 21202 into the search tool it will take you to the details straight away. The only thing which it does not tell you is whether you can use it abroad? In the UK texts to 21202 are free.
I can also confirm that, sadly, CPW have NOT updated their systems to integrate this service for their customers. It does NOT work on CPW O2 therefore.
