Sim Cards – Check your Coverage!

All our mobile phones are Sim free. This means you can simply insert your current Sim card from your old mobile phone, thus meaning you can keep your old number and network. Alternatively you can purchase a new one! Either on contract or pay as you go. It is entirely up to you!

If you are getting a new Sim card please check to make sure the company you go with has signal coverage in your area. Below are some of the more popular networks along with links to their websites to ensure they have coverage where you live.
