[Hidden-tech] Int'l phone calls

[eddygold at aol.com]

Seeking sugg'ns on how to talk to a friend traveling in Egypt and India, cellphone to cellphone.
It's not about SIM cards, which phones, plans, etc. -- I've seen those discussions.
I'm just looking for an alternative to WhatsApp. Maybe something here?:<!-- /* Font Definitions */@font-face {font-family:"ＭＳ 明朝"; mso-font-charset:78; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-536870145 1791491579 18 0 131231 0;}@font-face {font-family:"ＭＳ 明朝"; mso-font-charset:78; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-536870145 1791491579 18 0 131231 0;}@font-face {font-family:Cambria; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-536870145 1073743103 0 0 415 0;} /* Style Definitions */p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0in; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"ＭＳ 明朝";}a:link, span.MsoHyperlink {mso-style-priority:99; mso-style-parent:""; color:blue; text-decoration:underline; text-underline:single;}a:visited, span.MsoHyperlinkFollowed {mso-style-noshow:yes; mso-style-priority:99; color:purple; mso-themecolor:followedhyperlink; text-decoration:underline; text-underline:single;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; font-family:Cambria; mso-ascii-font-family:Cambria; mso-fareast-font-family:"ＭＳ 明朝"; mso-hansi-font-family:Cambria;}@page WordSection1 {size:8.5in 11.0in; margin:1.0in 1.25in 1.0in 1.25in; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;}div.WordSection1 {page:WordSection1;}-->https://www.maketecheasier.com/alternatives-to-whatsapp/
It's an iOS-to-Android phone connection, so no FaceTime, far as I can tell. We just want to talk -- don't necessarily need to see each other on the little screen.

This is probably simple -- I've just never done it before. 

Thanks for any advice,
Eddy Goldberg
