Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

Go to Settings>Security>Other Security Settings>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

 

Yes, as of March 3rd, 2020, OneSimCard eSIM can be used for Mobile Data, Voice and Texts. However, you can still use the OneSim VOIP app option with a Personal Extra Number (PEN) for additional savings on calling and texting

 

For DataMax eSIMs, only Data is available. However, you can use our OneSim VoIP app for cost effective voice and SMS communication.

OneSimCard SIM VoIP users with US and Canadian numbers may now send and receive text messages over the OneSim VoIP app on iPhone and Android. The cost to sending a message is $0.05 per text to most countries. Receiving message is $0.05.  

 

The main advantages are significant cost savings and the ability to call from countries where there is no voice roaming coverage available, or for DataMax or DataMax eSIMs

OneSim VoiP can be used from any Android or Apple ( iOS) device to make international LD calls even when you are not traveling. OneSim VoIP does not require having OneSimCard SIM being installed in the phone. OneSim VoIP can be used with Wi-Fi or 3G/4G - no difference. You just need to have OneSimCard account with the SIM VoIP capable PEN. Calling using OneSim VoIP will cost most of the time less than any other way of calling.

Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.

• If you have the OneSimCard Menu on your phone (it may be called Sim Application Menu on iPhones or SIM Toolkit on Androids), go to the menu, scroll down to Settings and enter Service Code 2003 and confirm, then Code 000 and confirm. For older SIM cards after this enter Service Code 1101 and confirm. Turn the phone off and then back on. 
  
  
• If you do not have access to the OneSimCard Menu then turn off your phone, remove the battery for 20 seconds, reinstall the battery and then turn back on your phone.

Some phone models do not allow direct dialing with older OneSimCard SIMs sold before January 1, 2017.

To get around this problem, you should try either of these methods:

• Locate the OneSimCard menu on your phone. (Some phones have it in Applications.)
  Make a call using menu 'Call'.
• You can also make a call by dialing directly *146*00 Country Code Number#
  For example, to make a call to the USA, you would dial *146*0018574440686# (do not forget to hit pound at the end of the number)

* is a star character located on the keypad

Other examples of how to use the *146* dialing prefix if necessary:

• To check your balance dial  *146*099# and press the TALK (or SEND) button
• To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
  where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
• You need to press * on your phone in the above dialing sequences (it is a star character located on the keypad)
• Activation of voice mail *146*091# and press the TALK (or SEND) button
• Deactivation of voice mail *146*090# and press the TALK (or SEND) button
• Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
• To listen to voice mail *146*095# and press the TALK (or SEND) button

The prefix *146* and # at the end can be used from any phone. However, newer OneSimCard SIM do not require it and you should be able to dial codes directly, 091, 094, 095, 099 or 098XXXX*XX Talk.

If you have an older SIM and the dialing does not work without entering *146*, please follow these simple instructions to remove the need to dial *146*:
