Machan…, this is best for couples or group talks. Moreover, mobitel is providing 1min as 1.RS rate and month rental is 150 mean normally Mobitel package provide you 150 min for 150.00RS. couple package is good because of once you pay 2000.LKR for two lines, you can talk 6 mount without paying any amount and lines will provides unlimited talk time and sms for dedicate lines in group. Next, dialling other numbers restricted because, one of user bill was more than 6000.00LKR earlier and I took 1000.00LKR as deposit. Then I paid 5000.LKR from my pocket resolve the bill. That’s why I put barriers for only one or more numbers within group. Finally, this is good couples or group talks and if you want talk to other numbers please use own mobile package.
