Blackberry Curve 9320 in Technical problems or questions. Posted March 11, 2014 She giving you this bill herself? lol My GF has AIS as well, and she chats/sms's her friends all day... and I pay about b1700 a month. The package we are on is unlimited internet (b800), 600 SMS + 700 minutes calling.. and she usually goes over a bit. I think the package by itself is about b1500. My package is b1200, with only 200 SMS and 200 minutes and unlimited internet, and I almost never go over, all of my stuff being on the internet. To be fair, a good deal of hers is too - Line/Viber. 5k baht means your either still using the cards and topping up her phone, or shes pocketing the difference. If your still on the cards... STOP IT lol. Get her to go to Telewiz and convert from 1-2-Call (AIS Pay as you go) to a AIS package that meets her needs... will save you a fortune every month.
