I have a PAYG mobile, £10 last me ages ,I tried to topup today, on line but couldn't and I couldn't understand because it's always so easy to do, I'm with Tesco and have found out that they've stopped PAYG now...they want you to take a bundle...you pay monthly, I don't know yet what it costs but I can imagine it will work out dearer then PAYG, just something else that folk have no control over, I'll have a look around other providers ...or maybe they're all getting rid of PAYG
