T-Mobile PAYG SIM with £5 credit, £1 in-store @ Poundland
If you’re wandering past a Poundland, you might fancy popping in to grab a T-Mobile PAYG SIM with £5 credit for – you guessed it – one pound. £5 for £1? That’s our kinda math.
Periodically available on eBay for 99p, too, though limited to 2 per household every 3 months.
Not available online. In-store only.
