Global SIM Card: Features

A Global Roaming sim

Tellink provides a single global roaming SIM card. This means you will receive a sim card which works everywhere you travel to and eliminates or reduces international roaming costs for voice, SMS and data services. The Tellink international sim card keeps customers better connected when they travel globally for business or leisure.

Other options?

• Disconnect your current number when you are travelling. Which means that you will no longer be reachable. ⇔ With a global SIM you stay connected everywhere you go.
• Buy local SIM cards? In every country you visit, you will have to buy a new SIM card and replace it, every time you cross a border. Unused credit will remain on these different local SIM cards. ⇔ With a global sim card, you have one sim card you can use accross borders without losing any connectivity

Tellink: USSD Callback technology

TELLINK Global Sim Card offers a SIM based service which aims primarily at offering important savings on international roaming charges.
To create savings on outgoing calls we use a callback technology which is natively embedded on the international SIM card and transparent to the user. Basically what we do is replace the outgoing call by an incoming call and a call to the destination. The arbitrage between outgoing and incoming calls enables us to offer substantial savings to our customers.
