About this app

SIJÚ is an instant messaging application currently available for Android, which allows you to use your connection (4G / 3G / 2G / EDGE or Wi-Fi when possible) to exchange texts and share multimedia content with your friends within Cuba.

Because we don't like to wait either: If your family member has data coverage in their area, we guarantee INSTANT messaging chat in real time!

Why you should use SIJÚ:
● SIJÚ automatically compresses your multimedia files (voice and photos), making it possible to upload and download them through data networks where the connection speed may be a problem.
● As long as your family member has an available connection (3G / 2G / EDGE or Wi-Fi, when possible), SIJÚ will receive your messages instantly.
● You will quickly know who has received your messages thanks to SIJÚ confirmations.
● Chatting with your Sijú and Nauta contacts in group conversations will make communication with your friends and family easier.

and much more: You can block contacts, select your theme, share contacts, set an image as your custom background, customize your notifications and much, much more.

Downloading the app is completely free. But you will need to pay a monthly subscription fee of € 2.50 to get this incredible experience and unlimited messages with your relatives in Cuba without them having to connect to the Internet.

* Your cellphone operator may apply charges for mobile data usage. Contact your operator for more information.

I liked this app in the beginning but now I'm not receiving any messages, and that really sucks since I just paid the $2.50 charge to have unlimited messaging and email. I'm thinking about deleting this app and unsubscribing from the service all together.

Super bad service, they made a new update and not able to warn that you could not uninstall the application and reinstall, now you just have to wait and wait, instead of looking for a solution, I recommend using Ditu, it is something more expensive but more reliable, responsible and serious
