Sim Card Compatibility

SIM card Compatible with Almost all unlocked devices

The Tellink SIM Card will work seamlessly with any mobile phone. You only need to make sure that you are using an unlocked phone. 

Nano, micro, and standard SIM cards – what do I use?
As technology advances, SIM cards are getting smaller to fit more powerful smartphones, which need that space for more hardware. At the moment, SIM cards come in three sizes: Standard SIM, microSIM, and Nano SIM.

If you’re unsure what SIM to use for your device – you’re in safe hands. Tellink's Multi-SIM card contains a Standard, micro, and Nano SIM. So, if you change phones in the future you don’t need to worry about getting a new SIM card.

Just put in the compatible sim card size (normal, micro or nano) and start using your phone as always.

Your phone may be locked if for example you purchased it on contract or through some other offer from your local provider. You can check if your phone is unlocked by inserting a SIM from a different network provider into your phone. If your phone is locked you will see one of the following messages when you put the SIM into your phone: ‘Insert SIM’, ‘Phone restricted’, ‘SIM not valid’, ‘SIM not accepted’ or ‘Wrong SIM’
