Tips for Using a “Mobile” in the UK

If you are traveling to the UK for a short trip, you may be wondering if you can use your cell phone (commonly referred to as “mobile phones” or simply “mobiles” in London). You actually have three choices when it comes to mobile calling in the UK:

1. Mobile Choices in the UK

1. Activate an international plan with your cell phone provider.
2. Rent an international cell phone.
3. Purchase an unlocked phone and SIM (Subscriber Identity Module) card that works in another country.

The first option, purchasing an international plan, seems like the simplest; however, it will probably be the most expensive. Most carriers charge a monthly fee (or one-time charge), plus a per-minute calling fee, texting fee, and data fee, which can be quite high for limited data. The second choice, renting an international cell phone, offers some convenience since the phone is shipped to your home with an initial airtime balance. Nonetheless, you will have to mail the phone back when you return home, and there is a daily fee—meaning you may end up paying for days you don’t even use the phone. Fortunately, pay-as-you-go mobile phones are very popular in London, with numerous retailers offering a variety of plan options.

2. Using Your Phone with a New SIM

If your phone is unlocked, you might be able to simply buy a new SIM card. This card, which contains the telephone number and network information, will need to be compatible with your current phone and the UK network you choose. Therefore, it is wise to consult your current phone provider regarding which UK SIM cards will work with your handset.

For instance, SIM card packages from Virgin range from £5 to £10 ($6.50 to $10.30) and are compatible with existing phones. Moreover, the Cellular Abroad service offers a World SIM that features lower rates for calls overseas—making it a viable option for keeping in touch with family or friends back home. However, remember that local call rates may vary, so assess your needs before selecting a SIM deal.

3. Getting a New Phone and SIM

If your phone isn’t unlocked, or if you cannot find a compatible SIM card—or you simply prefer not to use your personal device—a pay-as-you-go plan that includes both a handset and SIM card is the optimal solution. Often, these plans also come with some complimentary credit towards your calls.

Some of the leading mobile phone companies in the UK include Vodafone, Orange, T-Mobile, O₂, Virgin Mobile, and Three. Pricing for calls varies across companies, so remember to compare your options according to your requirements. Additionally, Londoners often send text messages rather than making calls, as text messages are typically more affordable—often five times less expensive than phone calls.

4. Understanding Pay-as-You-Go Plans

If all you need is a phone to make international calls, London offers many stores that sell prepaid handsets. These budget-friendly, no-frills phones come equipped with pay-as-you-go plans. This type of plan is a sensible option for short trips, as you won’t be locked into a contract. Instead, you simply purchase credit for the phone from various retailers, identified by “Top-Up” signs.
