1)Mercury Messenger: was the best solution out there.it includes msnmp21.but after the changes on 2014 it can’t sign in.I asked jonathan to fix it,but he couldnt do anything cause its ENCRYPTED and cant modify.it would be good if someone developer out there help if knows. the developers of the program who have abandoned it.if jonathan could reach the program,he can fix it.
2)Skype:its the official program so far.you can link you microsoft account (hotmail mail or ther) with skype,and have your messenger contacts.the bad thing is you have link skype but ok…
3)iwantim messenger android app https://play.google.com/store/apps/details?id=com.iwantim.iwi :
for me its the best solution out there:its a light weight program that you can have on your phone,and you must link skype with a microsoft account,you can create a blank skype account and linked it so you can have only your messenger buddies,its better cause its light.texting friendly and it kind reminds the messenger apps. it has basic functions like texting or send a photo etc.
hope to help you guys.
if someone knows other,please type it below. if there are any developers out there who would like to help please inform thanks
