  • Overview

Why choose an iD Mobile SIM-only deal?

iD Mobile is an award winning network, which benefits from piggybacking off the Three network.

They've won a "Which? Great value" mobile network provider award 2023 and also benefit benefit from the UK’s fastest 5G speeds (as rated by Ookla) through Three as standard. 

They also have comprehensive 4G coverage, using Three’s infrastructure to bring a 4G signal far and wide across the UK, with 99.8% of the UK’s population covered in all.

Plus, they offer a range of SIM-only deals that are just 1 month long. Given that most smartphone contracts are 24 months this gives you extra flexibility. But if you’d rather choose a longer-term plan there are 12-month and 24-month options too.

Benefits of choosing iD Mobile

  • Data Rollover

iD Mobile’s main extra is data rollover, allowing you to carry any unused data over from one month to the next, so you have a second chance to use it. Not many networks offer this.

  • Free Roaming

iD Mobile lets you roam at no extra cost in 50 destinations, covering most of Europe and even a few countries outside Europe, such as Kazakhstan.

  • Tethering

Tethering is allowed on iD Mobile, so you can use your data to get other devices online.

  • And more

iD Mobile’s SIM Only plans also include 5G at no extra cost and Bill Capping, so you’ll never end up spending more than you intend.

Wi-Fi Calling and 4G Calling are also included, and many plans come with up to 3 months free Apple TV+, Music, and Arcade at the time of writing.

How can I keep my number when switching to iD Mobile?

Keeping your number is simple. First you’ll need to get your PAC code off your current network, which you can do by texting ‘PAC’ to 65075 from the number you want to keep. Then, once you’ve activated your iD Mobile SIM card, just fill out this form.

Which size SIM will I get?

iD Mobile will send you a one-size-fits-all SIM card. This can be used as a standard SIM, or snapped down to micro SIM or nano SIM sizes.
