With oodles of options for every budget and usage need, Tesco Mobile's SIM only plans are some of the best value around. Plus, with perks like Clubcard points and free roaming, you'll get serious bang for your buck.

Why Tesco Mobile Is A Smart Choice For SIM Only

Tesco Mobile is a reliable MVNO that uses O2's sturdy network.

Here's why Tesco Mobile's SIM only plans are a savvy pick:

  • Affordable plans with loads of data
  • Unlimited minutes and texts on most plans
  • Flexible 12-month, 18-month, and 30-day options
  • Earn Clubcard points every time you pay your bill

Tesco Mobile's Network Coverage And Speeds

As an MVNO (mobile virtual network operator), Tesco Mobile piggybacks on O2's mobile network infrastructure. So you'll get the same reliable coverage and speeds as O2 customers. According to Opensignal, Tesco Mobile's 4G network delivers average download speeds of 18.3 Mbps and upload speeds of 8.1 Mbps.

While that's a touch slower than O2's 21.5 Mbps and 9.3 Mbps, it's still nippy enough for most folks' needs. If you've got a 5G-ready phone, you can tap into Tesco Mobile's 5G network in over 100 UK towns and cities. Tesco Mobile's 5G speeds are pretty impressive, with average downloads clocking in at 143.3 Mbps (Opensignal). That's faster than EE (133.5 Mbps) and hot on the heels of Vodafone (158.4 Mbps).

Family Perks & Clubcard Prices

One of the biggest selling points of Tesco Mobile is the chance to save even more dosh with Family Perks and Clubcard Prices.

Family Perks

Tesco Mobile's Family Perks lets you add up to 4 more SIMs to your account for a discount under family pack. The first SIM (the "leader") is the normal price, then each extra SIM (the "followers") is only a tenner a month. The best bit? The follower SIMs get the same allowance as the leader SIM. So if you've got the £30 unlimited plan, you can add up to 4 more unlimited SIMs for your family for just £10 each per month. A family of 5 could get 5 unlimited plans for a total of £70 monthly cost - a whopping £80 a month cheaper than buying them separately.

To set up Family Perks, you need to have at least one active Tesco Mobile plan. Then you can add extra SIMs through your online account or by giving customer services a call.

Clubcard Prices

Tesco Clubcard members can knock a few quid off their mobile bill every month with Clubcard Prices. For example, the 12-month 12GB plan is normally £11 a month, but only £9.50 for Clubcard members. That's a tidy £18 saved over the year. And the 30GB plan on a 24-month contract drops from £12.50 to £11 a month with Clubcard - a total saving of £36. To get Clubcard Prices, just link your Clubcard to your Tesco Mobile account through the app or website. Easy!


Roaming charges can be a real pain when you're trying to use your phone abroad. The good news is that Tesco Mobile offers free EU roaming on all its plans. That means you can use your UK allowances of minutes, texts and data in 48 European destinations, just like you would at home. And Tesco Mobile has promised to keep EU roaming free until at least 2025, so you don't need to sweat over post-Brexit price hikes.

For roaming further afield, you can buy one of Tesco Mobile's roaming add-ons:

  • Europe Zone: 500MB of data for a fiver a day in 30 non-EU countries
  • USA & Canada: 500MB of data for a fiver a day
  • Rest of World: 50MB of data for a fiver a day

Or you can just pay the standard roaming rates in over 200 worldwide destinations, but be warned - it's not cheap!

Keeping Your Number

Want to switch to Tesco Mobile but keep your current number? No worries.

Just text PAC to 65075 to get your PAC code from your old network.

Give this to Tesco Mobile when you sign up and they'll port your number over, usually within one working day.

Keeping Your Number

How do I keep my current number when switching to a Tesco Mobile SIM?

If you want to keep your existing mobile number when moving to Tesco Mobile, you'll need to request a PAC (Porting Authorisation Code) from your current provider.

You can get your PAC by texting 'PAC' to 65075 from the number you want to transfer. Your current network will then send you the PAC, which will be valid for 30 days.

When you order your Tesco Mobile SIM, simply provide this PAC at the checkout. Tesco Mobile will then arrange for your number to be transferred, which normally takes about 1 working day.

Once your number has been ported, your old contract will automatically be cancelled, so make sure you've settled any outstanding bills with your previous provider.

Bringing your number to Tesco Mobile is free - they won't charge you for the transfer.

Can I use a Tesco Mobile SIM in my iPhone?

Yes, you can use a Tesco Mobile SIM card in any iPhone, as long as it's unlocked.

All of Tesco Mobile's SIM only plans come with a multi-size SIM card, so you'll get a Standard, Micro, and Nano version to fit any iPhone model.

If you're not sure which size SIM your iPhone needs, here's a quick guide:

Can I use a Tesco Mobile SIM in my iPhone
  • Nano SIM: iPhone 5 and newer (including all iPhone 12, 13 and SE models)
  • Micro SIM: iPhone 4 and 4s
  • Standard SIM: Original iPhone, iPhone 3G and 3GS

To check if your iPhone is unlocked, simply pop in a SIM card from another network. If it works, your iPhone is unlocked and ready for a Tesco Mobile SIM.

If your iPhone is locked to your current network, you'll need to get it unlocked before you can use a Tesco Mobile SIM. Contact your current provider for info on how to do this - they may charge a fee.

If you're planning to use a lot of data on another device, it might be worth getting a dedicated mobile broadband SIM from Tesco Mobile instead.

All of Tesco Mobile's pay-monthly plans require a credit check.

So if you have bad credit, you might struggle to get accepted.
