Hi Daniel,
I've just read
here on MSE forum (posted by Pricefighter) that AbroadTel have changed their access number used for calling Mobiles to 0871 342 00 09 which is charged at 9ppm from a BT landline but will be more from other providers.
Also, AbroadTel's service, as posted on the MSE forum, is getting worse and sometimes you get informed that the mobile is off or busy even though you know it isn't.
I know this is true as I've rung my own mobile and a few times I'm informed that the mobile is busy even though I obviously know it isn't. This is worse because obviously once connected to AbroadTel we are paying for this service even if it comes back and informs us the mobile is busy.
I also read that OfCOM are looking into AbroadTel as they've received loads of complaints about this.
Therefore, taking into consideration the above I don't know if you want amend your Cheapest Call provider for mobiles back to Call1899 at 10ppm.
Kev.
