One should choose a carrier carefully and that too in case of international calling,sometimes its would become expensive if we opt for any, without prior knowledge.
Points to consider while choosing:
1. Network coverage?
2. How much Talk time do you use?
3. Do you text too much?
4. Do you need GPRS Data Connectivity?
If, you are planning to take the connection for both broadband and phone services, O2 is the best Best Broadband Provider at uSwitch 2012 awards.
Buy, carefully planning the above stats, one can easily select the carrier.
So, it’s safe to say that choosing a carrier is equally important as of choosing an accommodation otherwise one would be squeezed out.
