    I am absolutely disgusted with asda mobile, i called for a pac code a couple of days ago, and only because they could not sort a problem theycreated, i only phoned tesco mobile today gave them the pac code, they disconnected me about 6 which was before tesco had time to connect me over properly after i gave them the pac code i was given. My son rang me on the housephone just now, because they have already given my number to someone else before tesco have finished transferring. What the hell are they doing. Can you offer any advice please, this is going to create so much inconvenience.

      Hi Sue,
      I’m so sorry to hear about the problems you’ve encountered moving a phone number from ASDA Mobile to Tesco Mobile. Typically, it’s the responsibility of your new mobile network if something goes wrong during a phone number transfer. However, as I understand from your message, it was slightly different in your case that ASDA Mobile cut off your phone before the transferred occurred? If so, this isn’t the typical behaviour and as such, I wouldn’t really be able to give you any detailed suggestions. The chances are you’ll need to contact ASDA Mobile Customer Support to get this issue resolved: you can reach them on 0800 079 2732.

    I have recently transferred from Tesco to Talktalk mobile (last Monday) and for 2days I could make phone calls but not receive them. Dialing my number from my landline gave varying results from “You have dialed an incorrect number” to 2 ring tones then disconnected tone then “this number is not receiving calls at the moment”.
    Due to 2days of frustration I demanded the PAC code back and Transferred back to Tesco but the problem remained even with Tesco.
    Now a further 2 days without incoming calls (except from a friend with a Tesco SIM) I am again totaly frustrated.
    I have complained bitterly to tesco but still waiting. can you make any suggestions
    Regard
    Harry

      Hi there,
      I’d recommend calling Tesco Mobile Customer Services on 4455 (0345 301 4455 if you’re calling from another phone). They should be able to arrange for this for you.
      Hope this helps,
      Ken
