I talked to 3 customer service about 3 weeks ago. I have a Pay As You Go plan well before 2021. They told me the surcharge does not apply to me. I was real happy to hear that. If I remember correctly she said it was because I had been a customer for so long. Go to the 3 website and you can talk to a CS agent on chat, and ask them if PAYG is free roaming. I do get text sometimes of welcome to the US. You are in a free roam country. your minutes will come out of your allowance.
