Wife is going to the Philippines for a 2 week medical mission and we'd like to stay in touch with each other. She has an iPhone 5s, I have android. We thought about putting a package on her phone but $150 for 50 min and 50 texts is a bit extreme. Would put google duo on our phones but you need data for it as it uses your cell #. Skype is terribly fussy I find. Facebook messenger had a video chat that works ok, quality isn't great though. Suggestions?
