@maggie1234 anyone you normally have "green bubble" chats with should be fine. I think if you want to message other iPhone users while you are in the USA with just the US Roaming Texting add-on, you may have to change some settings in your Messages app, but I'm not totally familiar with the details. @Luddite @CalgaryBen @Rockdaddy22 could one of you provide more details on setting iMessage to only deliver over SMS/MMS for the duration of @maggie1234's stay in the US?
If you have no data, blue bubble people should automatically revert to green bubble people, no need to do anything.
Thank you. I left roaming and cellular on and it shows at&t I’m top right. That’s ok though right? I’m not roaming and being charged?
Remember, your service is with pm not at&t or T-Mobile and pm is prepaid. So if the service is not included in your plan it just won't work. No overages, even in the US.
