What is the correct way to dial Canada from Thailand using my Canadian phone?

I imagine phoning Canada from Thailand with a Canadian phone, which I surmise you mean has a Canadian phone number in it will more than likely be very expensive.

If you have a Thai SIM card in the phone then depending which carrier you are using, can vary on the price as some use a prefix number to reduce the cost!!!

Which I imagine would more than likely be cheaper than what you are trying to do!

I usually use messenger or what's app, or if I do have to phone to a landline or mobile I use the required prefix for cheaper calls

I use yolla working perfectly cost 1 cent a minute so 1 hour .60 cents

0111……….. or +1 …….

Use Fongo

The actual number is of course +1-###-#######

However, depending on how/where you are calling from, and what type of phone or business etc you are calling to. It can change how you dial. You may have to add a few numbers at the front. I DO remember using 001 AND 1 in front of the +1-###-#######

001 pour sortir de Thaïlande, ensuite 1 et le numéro.

Use mobile voipdiscount app

It might be +1
