What are the best VoIP providers for keeping a UK mobile number while in Thailand?

Lots of ways to do this

Best is a sip system, or setting like Google Voice. Redirect the mobile to the VoIP number and get SMS roaming free.

You can also use things like xpatphone. I don't like how the messaging works on this but that's personal.

I’ve been using Vonage for years. It comes with a UK landline number via a phone app and my plan (World Talk or smth like that) has appx. 65 countries coverage with FREE calls, some are only to landline numbers, some with both- mobile and landline, including Thailand. Free calls are up to 1 hour conversation. I’m paying £14.75/month and find it very helpful, especially when you are on hold with some companies, HMRC, etc.

NumberPeople (£5 a month)

Just keep your current UK mobile number and divert all incoming calls to your new NumberPeople number (which can run on a VOIP app on any phone). I use Giffgaff as my UK sim (£6 a month). Your divert won’t get charged because the divert is to your UK NumberPeople number from Giffgaff and the £6 a month includes unlimited calls. Total cost £11 a month.

Your outgoing calls are made on the NumberPeople VOIP app (which you can have on any phone), and will show as a UK based local number (you can choose your own area code)

Check out the Yolla app - it's superb. DM me if you want to use it, and we both get a free credit

Zoho voice

I use numberpeople and flextel, but porting in an existing number isn't cheap

I have a giffgaff PAYG, top it up and send a text every 6 months to keep it active, Mytello is another wifi based alternative.

I don't work but I keep a cheap UK contract with a mobile provider which provides free incoming calls from the UK and combine it with a service like Yolla for outgoing calls which show as coming from my UK SIM number. Dual SIM phone so can also make/receive calls in Thailand and use the Thai SIM for data
