I have done one of these before with no problems.. But have a question..
I can't get a answer from phones4u as the helpline is too busy.
I am on a deal, that gives 500 texts, but they are not enough....
I can upgrade the tariff with vodafone to get more, but I suspect this change of tarrif may affect the cashback???
I could also add a text pack onto my current tariff???
I am not sure if either of these actions may affect the cashback from phones4u??
