I. Should I Buy a New SIM Card for My UK Trip?
When visiting the UK, you have a few options to get mobile internet access:
- Use your home SIM card with roaming – This can work, but roaming data rates are usually very expensive. You may face bill shock when you get home.
- Rent a portable WiFi hotspot – These give you mobile data, but can be bulky to carry around. Hotspot rental pricing is similar to local SIMs.
- Buy a local UK SIM card – A UK SIM gives you affordable mobile data, calls and texts. It’s flexible since you can use it in your own phone. SIM cards are easy to find in the UK.
For most travelers, getting a UK SIM card is the best option. It gives you cheap data starting from around $10 per month. Calls and texts are very affordable too.
