I have an Iphone XR, I want to know if I can send and recieve text messages if in another country with my roaming off, yet using wifi only so I don't get roaming charges? Thanks
Welcome to the community!
Firstly, to clarify, are you referring to text messages (ie SMS and/or MMS) or iMessages? If you're referring to the former, text messages don't generally get transmitted via Wifi (except with Wifi-calling). If your device is supported for Wifi-calling, some usage abroad is considered roaming and would incur additional charges.

**edit** You should note that if Wifi-calling is not enabled, receiving SMS would not incur any roaming charges. However, any data contained within MMS (incoming or outgoing) would be considered roaming data. You also should note that multimedia message services (MMS) are not limited to just photo or video messages. Some phones allow users to add Subject lines to their messages -- similar to the subject lines found in emails. Adding a Subject line automatically converts a SMS to MMS. Depending on the phone and its settings, a blank subject line may also still be considered a MMS. Additionally, some phones will also convert long-SMS (messages exceeding the 160 character limit) to MMS automatically. **
On the other hand, if you're referring to iMessages, sending them via Wifi only would not incur any roaming charges. To prevent any unintentional roaming charges, you might consider enabling Airplane or Flight modes for the duration of your trip abroad. You could then manually enable Wifi when required.
Hope this helps 😀
