How to check if your sim card is still active

The following steps can be taken to see whether a sim card is still active.

To check if the sim card is still active, you can dial any Vodacom number on the device you are using e.g. *111#.

  • If you are receiving the Vodacom menu, it means that the sim card is still in a working condition.

  • Should you receive the message "Not registered on network" it either means that the sim card is not rica'd or the sim card is not active anymore, as it was not in use for three months or more.

Note: To make sure that it is really the sim card that is not active anymore, you may check the sim card in a different device and see if you are still receiving thesame message. If you are receiving the same message, than it is the sim card that is having the problem. Should it not occur on a different device it could be that the device is faulty.

Predictive Text Settings

Settings: Predictive Text.

  1. Predictive text guesses the word you are busy typing. You will see three options appear in the bar above the keypad. You can select any of the three options. The phone will automatically select the word in blue (middle) when you press space.

  2. When using business apps you may generally use terms or acronyms that is industry or role specific which might not be found programmed in the language settings of your every day technology. You might therefore find that having predictive text on frustrating because it tends to predict and select incorrect words/terms.

  3. We therefore advice our clients to turn off predictive text when using business applications.
