Tesco Mobile SIM Only Deals

Why choose Tesco Mobile SIM-only?

Tesco Mobile has partnered with O2, which means it has the same coverage as that network – namely comprehensive 4G coverage and widespread 5G, so you’re likely to get a good signal.

But Tesco Mobile also has some key advantages of its own, most notably low prices and a range of SIM-only tariffs, covering 30 days, 12 months, and 24 months, giving you a choice of extreme flexibility with the shorter contracts or big savings with the longer ones.

Added extras

Tesco Mobile puts value first, and that’s clear in the low pricing of its plans – you don’t get much in the way of extras, but nor are you paying for things that you might not use.

That said, if you have a Tesco Clubcard then you'll get 1 point for every £1 you spend on your plan, and Tesco Mobile also supports both Wi-Fi Calling and 4G Calling, so you can stay in touch when there's no 3G or 2G, or even no mobile signal at all as long as there's a Wi-Fi network.

Tesco Mobile also offers family plans, and it saves you money by capping your spending, so you won’t accidentally exceed your allowances.

Data roaming

Tesco Mobile lets you use your allowances at no extra cost in 48 destinations, mostly those within the EU. A lot of networks now charge for roaming, so this is a handy perk.

Tethering

There’s no limit to the amount of data you can use for tethering on Tesco Mobile (other than your general monthly allowance), so you can get more out of your contract by using it to get tablets, laptops and other devices online.

How can I keep my number when switching?

To keep your number, you first need to get your PAC code from the network you’re leaving. The easiest way to do this is just to text 'PAC' to 65075 from the number that you want to keep.

Once you’ve done that, just text 'PORT' to 23424 from your temporary Tesco Mobile number. Then simply respond to the texts you get in reply, supplying them with your PAC code and the number you want to keep.

Which size SIM will I get?

Tesco Mobile’s SIM cards fit any phone, you just stick the full-size card in if you need a standard SIM, or pop out the micro or nano cards if you need something smaller.
