I know this is an old thread but does anyone know of any payg or 1 monthly providers that allow you to pay the bill early? Smarty lets me top up in a shop and they use that cash for the bill, any others that can do that? Thank you.
Melissa said:
Hi Ken,
Please help. Is there any sim contract in the world that does not include any data? I need a mobile phone set up with absolutely no possibility of internet access. So ideally would be a large old fashion sim (not micro sim) for an old style Nokia phone, with only calls and texts. Thanks.
Ken replied:
Hi Melissa,
Thanks for your comment. Yes, you can go for ASDA Mobile’s £4 deal which gives you unlimited minutes & unlimited texts with no data. Alternatively, consider a Pay As You Go SIM for light users. All of those networks will give you an old fashioned Standard SIM card (the only one I’d avoid would be Three as they don’t support 2G phones on their network).
Hope this helps,
Ken

Hi Ken
Some months back I purchased a brand new SIM free Samsung Galaxy A20e with a view to switching from my present Samsung Galaxy J3 model – (purchased from EE and presently use on a pay-as-u-go basis) – believing my J3 SIM card would fit the A20e model – wrong!
So now I’m thinking of arranging a SIM only contract with another provider but wonder whether I have to purchase a mobile ‘phone from them before going forward?
Ken replied:
Hi there,
Thanks for your comment. No, there’s no need to buy a mobile phone from the other provider. You can simply order a SIM-only deal (like one of those listed above) and that SIM card can slot inside your SIM-free Galaxy A20e.
Hope this helps!
Ken
