I'm in Kalutara and I use Mobitel as my cell phone carrier.
1. I am a pre-paid user. The cost for sms and calling is fair and consistent compared to other carriers.
2. Good network coverage for calling/sms, not so much for data coverage
3. Data limit is poor compared to other carriers
4. Not good enough data coverage
5. Customer service is aceeptable
6. Compared to other carriers call and sms services are good with Mobitel. But carriers like Hutch, Airtel offer better data plans than Mobitel.
