The United Kingdom is just a stone’s throw away for Europeans. The capital city is popular, but countless tourists travel to rural areas every year. Every year, young people choose to study abroad in the UK to learn English or improve their language skills. They turn their backs on their home country for a few weeks to a year. Many people are also drawn to Great Britain for business purposes. They all have one thing in common: they usually don’t want to live without their mobile phones abroad.

Staying in touch with friends, relatives, and acquaintances is essential during a stay abroad. Some prefer to make phone calls, others send emails or surf the Internet. Many hotels, restaurants or department stores offer free Wi-Fi access, but this is not a solution for using your smartphone while on the move and also for making calls. To be able to make cheap calls and browse the mobile internet abroad, a prepaid SIM card for England is recommended. If your current SIM Card is used abroad, there are high roaming charges. It is therefore advisable to use a local England SIM card, especially for calls abroad.

FAQ - SIM Card United Kingdom

Which Network is the Best?​

There are some providers active in Great Britain, which are also known worldwide. The international providers T-Mobile, O2 and Vodafone operate their own networks with different offers in England. They issue SIM cards on a prepaid basis with different conditions. For example, the Pay & Go offer from O2 is attractive for internet users. You pay 10 pounds for a volume of 500 megabytes, which is equivalent to around 14 dollars and can be enough for an entire month if you surf occasionally without large video streaming. However, the activation can take a few days. In addition to the network operators mentioned above, some other providers are available but are less well known.

A good alternative to O2, Telekom, and Vodafone is, for example, provider 3. With the UK prepaid SIM card, which is sold in England as a pay-as-you-go card, you can conveniently load a data volume onto the card. Daily flat rates with a limit of 120 megabytes are also cheap. The cards can be obtained on the Internet. A 3G-compatible cell phone is required to make phone calls with the card. It is not possible to make calls using the Three SIM Card with simple GSM cell phones. The provider GiffGaff, which uses the O2 network, offers UK SIM cards for mobile use with a good price-performance ratio. Other providers are Orange, Lyca or Lebara.

Prepaid SIM Card or Roaming?

It is not worth taking signing a mobile phone contract for a limited stay. Although the fees are often cheaper, you are bound for the entire term of the contract. If you return home, the contract must be continued. Besides, it is not easy to fill out a contract abroad. Foreigners often fail to notice pitfalls and special features because their language skills are not sufficient. Abroad, you cannot assume that the same rules apply as at home.

A UK prepaid SIM card is, therefore, a good alternative to a cell phone contract. It also offers full cost control. With a prepaid card, you can only phone or surf as much as you paid in advance. At the end of your stay, you won’t have an unexpectedly high bill. With a credit check, you can see how much credit has already been used. If the credit is exhausted, calls or SMS are no longer possible. The Internet will then also no longer work.

Where can I buy a UK SIM Card?

If you are an EU citizen, you can buy a SIM card from a local network in any other EU country without having to be a resident in that country. You don’t even need an ID to buy a UK SIM card. You can buy the cards either on-site or in advance on the Internet. Anyone looking for a prepaid card for the UK should do so under the search term “pay as you go sim” to avoid expensive surprises.

Numerous different UK prepaid SIM cards are inexpensive and do not generate high fees even during use. Prepaid SIM cards for England can be obtained from various providers on the Internet, but also from some online shops that specialize in the sale of foreign SIM cards. You can buy top-up cards for different providers everywhere. Most providers offer online top-up as well.

What SIM Card packages are available?

There are different variants of the England SIM cards. Some focus on phone calls and text messages, others have a data volume to enable mobile access to the Internet. There are SIM cards in England with flat rates for calls, internet or SMS, which are a little more expensive than cards with billing to the minute, but also offer more freedom. However, especially flat data rates are mostly limited to a certain data volume.

Requirements for the UK SIM Card

If you want to make calls and surf on the phone in the UK, you usually have to pay very little attention. Only the size of the SIM card required should be taken into account. For example, iPhones need micro-SIM cards that are not available everywhere. Larger cards can, however, either be cut to the correct size with scissors, or some stores also have a tool to adjust the card size. A prerequisite for mobile phone use abroad is that the mobile phone is unlocked. A locked smartphone can only be used with a specific SIM card or in a specific network. In most cases, the lock can be removed free of charge after two years. However, many cell phones are sold without such a lock.

Mobile Internet on Laptop

There are various options for using a netbook or laptop abroad. You can try a surf stick but the device has to be unlocked just like your smartphone. If a cell phone and tablet with internet access are needed, a second prepaid card for the UK is required. Alternatively, the smartphone can be used as a hotspot to which the notebook can connect to for an internet connection.

Of course, a prepaid card with data volume can also be used in an iPad or a netbook if it is the right size. However, it must be noted that many Internet options abroad have to be booked or canceled via SMS. However, the iPad is not designed to send SMS. So to be able to change the options, the card must be inserted into an unlocked cell phone.

An alternative is an app that allow SMS to be sent via the iPad. If the Internet is opened for the first time in England with the new prepaid SIM card, the data services should first be switched off because many of these services automatically connect to the network, update data or download updates. If the right tariff has not yet been set, this can quickly become expensive before the user has even started surfing. If the Internet then works at the correct tariff, the services can be switched on again. However, it is advisable to check automated updates carefully and, if necessary, switch to the “manual” option. The download of updates can be started manually if a WiFi network is available without using the data volume of the prepaid card.

London is a popular destination for tourists. To enjoy your vacation on the island, you can order a SIM card for England in advance.
You can simply order an English SIM card over the Internet and put it in your smartphone right away.

Depending on whether you want to make calls or surf the Internet in England, you can save a lot with a corresponding tariff.
