UK SIM Cards: Cheapest Prepaid

Best sim only providers the UK

Many carriers issue the cheapest prepaid SIM cards with no monthly fees . Free inbound calls in over 100 countries, not pay high roaming charges when traveling abroad.

Mainly including the following UK phone plans:

  • Pay as you go, you can buy a card and use it directly in this phone plan, and then you can continue to use it if you continue to recharge it when it is used up. If the phone bill is not enough, you can recharge it at any time, and you can usually buy recharge coupons in street supermarkets, which is very convenient.
  • SIM Only Mobile Phone Plans, this phone plan is a well-known package model, with regular deductions, generally including 30 days without a contract and 12 months with a contract, and generally requires the ID card and addresses, which can only be obtained after a credit review.
  • Contract Mobile Phone Plans, this plan is also what we often call contract phones. Generally, contracts ranging from 12 months to 24 months are signed in advance, and then a certain amount of call charges are returned every month. If you just want to change your phone and you’re in the UK for a long time, this option is also more cost-effective.

The difference between Sim Only and Pay as you go is that Pay as you go can be bought by everyone. You do not need to verify your identity and do a credit check, such as phone card vending machines at airports and railway stations. There are pay-as-you-go cards sold by various companies.

You don’t need any identity or address information at all. You can use it directly after you buy it and charge it. It is worth noting that even if many companies are Sim only 30 days (30-day SIM-only package), they still need to show your ID, address, and review your credit before deciding whether to sign for you.
