coralia Posted November 22, 2018 Share Posted November 22, 2018 Is there a place where I can buy a Thai SIM card upon arrival at Suvarnabhumi? Or add money to my old one? Link to comment Share on other sites More sharing options...

KneeDeep Posted November 22, 2018 Share Posted November 22, 2018 AIS/DTAC/Truemove H all have booths in the arrivals hall. But just top up existing SIM at Family Mart if still active. Link to comment Share on other sites More sharing options...
coralia Posted November 23, 2018 Author Share Posted November 23, 2018 I'm not sure if it's still active... I haven't been in Thailand since February. I would rather go to a DTAC booth if there is one than to Family Mart... I have a new phone and it's supposed to be dual-SIM. Does this mean that I can use a Thai SIM and the SIM from my country concurrently...? I apologize if this is a stupid question ????..... Link to comment Share on other sites More sharing options...
Aachen Posted November 23, 2018 Share Posted November 23, 2018 Put the card into a mobile phone and check whether it logs in. Then check you balance. Or call the nbr. Link to comment Share on other sites More sharing options...
petesc55 Posted November 23, 2018 Share Posted November 23, 2018 If your local phone has coverage of some sort in Thailand it will work. You usually have options in the settings which sim card to use for calls, internet, messages, etc. I'd check with your home phone provider to make sure what coverage you will have, and at what price? Dtac has a booth in arrivals. Unless you set your card up to stay active before you left thailand, paid the minimal fee to extend the activity of the card, up to 12 months, I think, it has been deactivated. I forget the fee to add months of activity to your phone BEFORE you leave thailand, but it's not much. I remembered to do this the last time i left thailand. I don't think there is any way to check if it's active unless you are in thailand, even if you paid the fees before leaving thailand. When you go to the dtac counter they can check your old sim card, but it's probably pointless. Link to comment Share on other sites More sharing options...

petesc55 Posted November 24, 2018 Share Posted November 24, 2018 I never figured out how that worked (From abroad) with a Dtac sim card, when the dtac sim wasn't set up previously to work in another country before leaving thailand. (from the phone itself, unless there is someway to set up an online account you can do from a computer?) I topped up my number from abroad last year a few weeks after leaving thailand without doing anything. The money just vanished. I think I did it correctly this time, using the code to add months to the number before leaving thailand. Got the confirmation texts. I will see in 4 months when I go back.

(from the phone itself, unless there is someway to set up an online account you can do from a computer?) There's no need for any special setup to the SIM prior to leaving Thailand. Turn on your phone with your DTAC SIM inserted wherever you are in the world and let it pick up the local network. Head on over to the DTAC URL and type in your Thai phone number. Then you'll receive a SMS with a 4-digit OTP. Enter the OTP into the website and head to Jaidee services then Jaidee Day Give-away. If you haven't enough credit then topup with your credit card. I leave very little credit on the SIM once I've left Thailand and only topup with roughly the amount I require. https://my.dtac.co.th/esv/en/login Link to comment Share on other sites More sharing options...

I suspect you're losing balance on data roaming rather than SMS, in fact I'm absolutely certain of it. Turn off data roaming which doesn't affect your ability to receive SMS.

But I know for a fact that I've never been charged for receiving DTAC SMS in my home country. As soon as I turn on my phone with my DTAC SIM inserted then I'll receive at least half a dozen spam texts and never been charged. Same vice versa, if I receive a text in Thailand on my home country SIM I also don't get charged. This is a well known fact that receiving SMS doesn't incur charges, but sending SMS abroad will incur a charge. Something else going on with your plan.

And you can probably control your sims via settings on your phone (ie set it to use both, or one or the other) Link to comment Share on other sites More sharing options...
The Fat Controller Posted November 26, 2018 Share Posted November 26, 2018 For prepaid DTAC SIMs International Roaming has to be activated using the APP or the website, so if the OP is already out of Thailand there is no way to get the OTP if they cannot connect to a local network. IR works fine, and you can add validity as long as you can get the OTP and have credit. Credit can be added easily overseas if IR has been enabled.

owenm Posted November 26, 2018 Share Posted November 26, 2018 On the question of whether your DTAC sim will work in your new dual sim phone will depend solely on the sim type.. Many duos now accept nano size sim cards for both sim 1 and 2.. Others may be nano for sim 1 and for sim 2 either Micro SD for additional phone storage, or micro sim or nano depending on your phone.. Mobile data and/or roaming if set is usually only active on sim 1 slot with 4G.. Sim 2 slot only 3G and Internet only via WiFi.. If your DTAC sim is the wrong size can usually be replaced with correct at no charge, but most now enable you to pop out the external frame of your sim to make nano size..

Yes you can have both sims in the phone at the same time but you need to be very careful with your preferences if you want to have them both active at the same time, can be quite confusing. I got fed up and now only have one active at any one time. If like me you decide to switch from one to another you do not need to worry about preferences but on switching back have to remember to switch off data again, there are 2 settings for data, data roaming and data usage.

THE REVERAND Posted November 28, 2018 Share Posted November 28, 2018 Simple when you arrive buy a sim card at airport there are many to pick charge it with 100 bht then next day see if both work. If they both work then you have a backup. You will spend 125bht sim n top up. The cheapest insurance you will get in Thailand. Link to comment Share on other sites More sharing options...

When ever you need, you can deactivate either SIM if you prefer to stop incoming roaming calls, and activate same when necessary (saves battery too!). Data roaming can be very expensive. Hence, if you are not very familiar with the settings, please ask someone who does to explain how it works. A very convenient facility, when used correctly. Normally, international incoming SMS are free - useful for OTP. Link to comment Share on other sites More sharing options...
observer90210 Posted December 5, 2018 Share Posted December 5, 2018 Change your phone operator. You can still keep the old number I think. Not sure however if the process is fast and if it can be handled at Swampy Airport. Link to comment Share on other sites More sharing options...
