T24 sim will be costly and very poor service in rural areas. When I went Coimbatore I buy an t24 sim in the big bazaar market where I shopped.
Total cost of sim is 149. talktime was 50 rupees. After 3 days the sim was not activated.when I call the customer service with charges no response I will go to big bazaar and activate sim. Call cost is very high per minute pulse I have for 1.50 rupees.
SMS cost will be high lot of disturb with the company sms also. When you go to high shopping mall like big bazaar please dont purchase the t24 sim.
