4evermaat Posted January 1, 2014 Share Posted January 1, 2014 I got prompted to upgrade my service to 3g 2100. I assume that I am currently on the 'legacy' service. I'm a bit confused as to why the change is not automatic if it is the same for mobile . Meaning, is is two separate companies or services (regular 3g and 3g 2100)? Is the voice any different? If they are the same from a billing or service perspective, is there any disadvantages to upgrading the service from legacy to 3g 2100? I did the online and *570# check and I am 'pre-qualified' for the upgrade . I'm just a little nervous about switching. I also wanted to do it for wife, which would give her a new base rate of 99 satang/min for all networks. She currently has 1.50 bt/min phone if she doesn't use any of the other temporary promotions (mao mao). In Chumphon Town. Link to comment Share on other sites More sharing options...
lomatopo Posted January 1, 2014 Share Posted January 1, 2014 AWN is a subsidiary of AIS; this is required to track auction revenue from concession revenue. The GSM 900 concession will end in 2015 so eventually you'll have to change, If you want/need 2100 MHz 3G then you should change. If you are fully satisfied now, then maybe no hurry to change. I can't think of any disadvantages except maybe different expiration/validity dates. Maybe switch you or your wife first, see how things are then decide on the second number?
