Been in Bangkok a couple of months,when I left our home in Isan I could get a signal on my old Motorola on my DTAC sim card. I bought my wife a Motorola V3 and took it back today, she gets a two bar signal on her old trusty Nokia but when she put the sim in the Motorola nothing at all, and my own Motorola doesn't pick up a signal either, is anyone else having problems also I can't get a signal in Bangkok when inside my hotel with the DTAC sim, is it the phones or is it Dtac sim cards.

Any help much appreciated.

DTAC = no good out here

123 Call = good

That's what I learned a few months ago when trying to call my gf from outside the country. She had DTAC and it was a nightmare. So she switched to 123 Call and I could hear her and she could hear me. Now, we're both living out here and both of us use 123 Call (AIS) and no signal probs. Hope that helps...

Thanks for the reply seems everyone I speak to is of the same opinion guess we'll just have to change over, a pity though cos we've got the Isan tariff where all credit you add lasts for 365 days.

One potential cause for less coverage is that AIS is 900MHz and DTAC 1.8GHz.

Anyway, I am using DTAC and I have no problem with coverage in the areas where I spend time. I have another problem - I used to subscribe to their B999/month unlimited GPRS/EDGE plan. In the beginning it was great, but it has been deteriorating. The last couple of months I have just been getting really slow connections that are disconnected very frequently. Last week I had enough and cancelled it as their customer service were not able to help. (The only response from customer service was "we are upgrading our network, it will soon be better".)

Now I am looking for a replacement, probably Hutch. Does anyone have a link to a coverage map for their data service, and up to date pricing?

Really not enough information to make an educated guess. Are you staying in one place? When you go somewhere else does the signal strength improve? When you have a signal how is the call quality? I'm confused about how many phones you have, and which one's work? Can you borrow a 1-2-Call SIM and try it in one of your two or three phones?

Generally speaking DTAC has excellent coverage in the metropolitan Bangkok area and has been building out their network country-wide, especially in 2006. It is true that GSM1800 (DTAC's network technology) supports smaller, but with higher capacity, coverage areas, but I've never experienced a coverage issue with DTAC in 3+ years.

There was also a question about GPRS in this thread. AFAIK Hutch does not have a GPRS network as they are a CDMA network provider. 1-2-Call has very good coverage for GPRS, and has many more EDGE-enabled base stations than DTAC. There are many issues affecting GPRS performance, for example voice calls take priority so when a lot of people start making calls your lose GPRS time-slots, but you are also on the providers' (DTAC, 1-2-Call) internal IP network so subject to various load factors. DTAC'sGPRS/IP network may just be overloaded as a lot of people signed up for the unlimited usage package?

I am not familiar with True Move's GPRS capabilities.
