Frequently asked questions

SIM only is just the SIM. That’s it. No strings – just minutes, texts, and data to use in your current phone. You can choose a pay monthly SIM or a pay as you go SIM and take it from there.

Ease. If you’ve just picked up the iPhone 13, iPhone 12 or Samsung S21 FE and have no intention of changing now, then just buy the tariff of minutes, texts and data you need and keep your favourite handset. If you’re looking for a phone, then check out our current mobile deals which include the latest Apple and Samsung ranges.

If your phone is 5G-ready, then pair it with our 5G SIM contracts. If you’re not sure if your phone can use a 5G network, check our page of 5G phones to double check.

All Tesco Mobile SIM plans come with our tri-SIM which fits phones with different sim size requirements. It’ll work with everything from your Samsung A23 5G to your iPhone 12. A simple solution where one size fits all.

That depends! Use your existing bills as a guide or head over to our mobile data calculator to estimate how much data you need based on your current or intended usage.
