I use to have O2 SIM card pay as you go only and used to top up £10 and get 300 free text messages to any network for a month and keep my £10 credit to use for the remaining months, which use to last me about 3-4months. I lost my phone a couple of months ago along with my SIM card and I'm now looking for a new pay as you go SIM card which allows me free texts and allows me to keep my credit which I topped up. Does anyone known of a free pay as you go SIM card that allows this as I hardly use my phone and don't want to be tied into a contract nor do I want to buy a bundle as this would expire each month which I wouldn't use. So I'm looking for a SIM card that allows me to keep my credit as well as an extra benefit as before with O2 of the free 300 text. Anything similar to this would be appreciated as I can't find anything, I would only want free minutes or texts messages. I have a sony experia l c2105. Any help would be appreciated.
