You might have subscribe to other services on tigo, all you have to do is just reload the credit and wait for your message and start browsing, the idea is not to use the sim card for any other purpose apart from browsing.
Now, if you load 1cide you get 400mb and if you load 2cide, you get 1000mb(1gig),, now you need to use the data within 24hours,
that means if you load credit to it @ 7am ,it automatically subscribes and gives you the corresponding amount amount of data base on how much credit you loaded onto the sim.the data then expires 24 hours later whether you have use it or not..
1.Now in-case you consume the data few hours after you load you credit, you can just load your credit at midnight 12:00am, and it will automatically subscribe again by itself. without waiting till 7am the following morning.
Don't rush to subscribe again or subscribe to any other tigo service for that matter , you risk getting it blocked or cancelled . just leave the sim card as it is.
