Please help me! I am about to go on a cruise, and want to be able to use wifi calling on my A25 phone. I cannot get it to do so. I have tried every suggestion I have seen online โ I put the phone in airplane mode and make sure that wifi and wifi calling are toggled on. I have tried toggling wifi and wifi calling on and off, toggling airplane mode on and off, toggling data roaming on and off, I have rebooted the phone โ I have even reset the network. No matter what I do, when I attempt to make a call, a popup tells me to turn off wifi calling. It will not receive calls, either. But, it will send and receive text messages with no problem on wifi and wifi calling with airplane mode turned on โ just no phone calls.
My wife has an A36 phone, and we also have a OnePlus phone. We have no issues with wifi calling in airplane mode with either of them.
What the heck is going on with my A25? I am doing everything that is suggested, and I have no issue with the other 2 phones. Help!
Both my A25 and my wife's A36 are on Mint Mobile (A T-Mobile MVNO), which allows wifi calling, and of course her phone is working fine. The OnePlus is on a T-Mobile prepaid plan, and also has no issues. I had thought about your suggestion of swapping to the OnePlus, but the apps, contacts, etc. are all different, so it would be a poor bandaid approach without solving my problem for the future, since I have a number of lengthy trips planned for next year, too, and really just want to be able to use my own phone. I would go through the trouble and time of a factory reset if I was confident that it would solve the problem, but I have no clue if I would be wasting even more time for possibly no good effect.
You can back up your phone using smart switch either to your computer or a thumb drive very easily. The whole process should take less than an hour of your time.
Have you tried a wipe cache partition on your A25?
Power off your device, while powered down, press the power button and Volume up button simultaneously until the phone vibrates and you see the Samsung logo. You will now be in the bootloader menu, using Volume for scrolling and power for yes, scroll to Wipe cache partition, press power, scroll to yes, press power, reboot, press power.
Have you ever used wifi calling on that device before? In many cases, you have to have an E911 address registered, and have made at least one phone call over wifi. You can do this by putting wifi calling on and connecting to your wifi network and making sure wifi preferred is on in the call preference setting. It should automatically switch to wi fi calling when connected. Do not put it in airplane mode until that first call is made. After that, it should work in airplane mode. If that doesn't work, contact your carrier for assistance.
Also, be aware that at least two cruise lines do not support wifi calling on any tier plan, and others do only on the premium tier.
If all else fails and you don't get it sorted before your trip, you can use WhatsApp or Google Meet for communication over wi-fi.

Yippee! That was the solution - I had not yet made a wifi call at all while I was trying to use wifi calling in airplane mode. But once I made a single wifi call without the phone being in airplane mode, and then switching to airplane mode and attempting a wifi call again, it now works like a charm. Many, many thanks for your help!
Additionally, you are correct that I may or may not be able to actually use this feature on a cruise ship now that I have enabled it. It seems unclear whether my cruise line allows it al all, allows it only with the premium streaming package, or it depends upon the ship. I will find out within 2 weeks. But I know now that I am fine for wifi calling at hotels, restaurants, gift shops, and other places that offer free wifi while traveling overseas. Again, my thanks for being so spot on and so helpful.
Carnival (and it likely includes Princess - same company) and NCL are two that I know don't support wi-fi calling on any wi-fi tier, at least they didn't as of two years ago. Royal Caribbean and Celebrity support it on the streaming tier.
