Do Thai Sim Cards Work In Singapore

[torrenova]

Does anyone have accurate information on the ability for Thai SIM cards to function in Singapore. I'd like information about all cards but specifically AIS 1-2-call prepaid.

If it does or they do, any information as to costs for calls out, incoming and SMS both ways would be much appreciated. Can you also top up from abroad, presuming they work ?

Thanks.

I've always had problems getting the service to work in some countries even though its suppose to function. Its best you contact service center at 1175 to make sure you have roaming enabled. Their english speakers are very helpful.

Yes, AIS is good for Singapore.

[Prakanong]

Yes, AIS is good for Singapore.

I would go along with that ;-)

I have forgotten to take my AIS card out before and put in my Singtel

OP - it might be cheaper just getting a pre-paid Singapore SIM though - you need to show passport or Sing ID card to get one.

Agreed, AIS is fine for postpaid, but Torrenova said prepaid and I don't know about that ... recommend the advice to call the service centre is followed to avoid any nasty surprises ...

Edit: or what Prak suggested - get a SingTel prepaid - absolute doddle and likely to be cheaper than a roamed service

One-2-Call pre-paid does allow for international roaming. You need to register first. Call 1175. Tarriffs are quite steep: 50 THB/min for incoming calls and calls to Thailand, 78.54 THB/min. for local calls. Not sure about SMSes but think they are ~ 10 THB ea., You can top up when roaming, if you have a card with you: *120*13digitpin# send. Making calls when roaming is challenging: *131*phonenumber# send, wait for callback.

Email One-2-Call [email protected] or ring them at 1175 for the latest information.

I'd get a local SIM in Singapore as you will save a lot of money. Then leave a greeting on your One-2-Call number with your Singapore number.

You'll have to check with DTAC but they can be more restrictive re: international calling, roaming and texting.

Have 1-2 call prepaid sim. Always had probs with roaming . They tell you to make a call put this number in front of the normal number but for me it just does not work.

Get a Sing sim easy!

If being available on you Thai number is important for you, get a second phone with a Sing sim card, or get the Samsung Duo, which takes two cards.

Your phone will always ring, and you can immediately decide whether to pick up, or call back with the Sing sim.

Both on post paid and pre paid the roaming can work erratically, I often get one way calls, where they can here me in Thailand, but I can't hear them. Call get's charged though at their high prices.

Cheers for the help folks.

Just another point. If roaming was available and working and the Thai SIM was used in Singapore, then what number would I see here ? Would I see the Thai number (name if stored) or some miscellaneous number or the "no number" thing ?

Thanks

I cannot figure out what you are asking?

Are you asking if a One-2-Call user roaming in Singapore were to dial a phone number in Thailand, would CPID (your Thai phone number) pass through and be displayed to the called party? The answer is no, the called party would see a AIS trunk number displayed, not really miscellaneous or random but unknown to you, the recipient of the call. It is actually a bit weird to be the called party, from a roamer. If you are roaming you "place" a call by sending a text message, *131*668nnnnnnnn# SEND. The SMS gets routed to AIS, they verify credit balance, authenticity, then make a call to 08nnnnnnnn, wait for an answer, play a greeting, then ring your phone in Singapore and connect the calls.

A local SIM in Singapore will save you a lot of money, not just on local calls but the providers there have low-cost (VoIP trunks) international calling options, a la "009" here, but even less expensive.

FWIW, I used to use M1 in Singapore, and was quite happy with their pre-paid service.

With a post paid account (gsm advance) the caller ID works most of the time. When calling from abroad using the Thai sim, the receiving party in Thailand sees your number about 70% of the time, the other 30% unknown number or private number appears!

With post paid accounts, you do not have dial a special pre-fix when roaming, just +66 and the local Thai number...

Same vice versa, you van pretty much always see who's calling you...

I used them as well before my postpaid Singtel and they were fine.

They have the best deal now on mobile internet connection with unlimited data (Singtel give us that on a company deal but only 50 Gb to the public)

I've used my Thai phones in Singapore, Burma, Laos, Cambodia and Hong Kong. Worked after a much longer "system registration" period than other SIMs (Western) I have had in the past which synced up to the local mobile provider as I walked of the plane. Incoming calls can be expensive depending on your tarrif with 1-2-Call.

Emails to 1-2call are normally returned quickly with useful answers.

But I suggest writing simple questions in very clear English that can be answered yes/no.

I 2nd what a lot of members have said when they say get a local sim. I'm down in Singapore a fair bit and use a local M1 sim card. With the prefix 021 there is no IDD charges and hence dirt cheap to call Thailand. Incidentally, if anyone from Thailand then wants to call your Singapore number, with the prefix 009 it is only 5 baht.

Got a call from an AIS pre paid yesterday which did recognise caler ID and came through with the user's number. However, A couple of SMSs I sent arrived but the recipient was not able to tell that they came from me by the number, only by the content.

I honestly cannot figure out what you are trying to do, or not to do?

Where are you?

Where was the AIS pre-paid subscriber?

How did you address the SMS'es you sent?

Could the AIS pre-paid subscriber originate SMSes to you?

Can you describe the 'experience' when they called you? Did they use the *131* scheme?

Perhaps AIS/One-2-Call are passing the Thai phone number through when connecting the calls; they didn't use to do this, at least not from the U.S.A. and a few European countries, in my experience.
