I've a question about VM 'sim only', I am a VM customer and some years ago set up a sim only deal which still tallies at 300min/300 texts per month at a cost of £10.70 (ish), and have been satisfied with this and it has served me well, hardly ever overrun, however see now a tariff at £6 a month with a similar or better deal are available I know it probably means changing numbers, and not a problem for me, but what do I have to do cancelling the old number, and is there something I'm missing that I should be aware of if I make this change >as I just can't see the point in paying £10+ when £6 gives me the same or better -it's virtually half the price! Would I be a mug not to change?
Oh, and I am a phone numpty - if I have a new 4G sim, will it work in any phone? Don't laugh but my mobile phone has a keypad. e.g. phones that are not equipped for 4G (obviously not on 4G though)
