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*:

How to activate compatibility mode:

 

 1. Locate OneSimCard Menu.

 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

         On Androids it is called SIM Toolkit app and it looks like one of the apps

1. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
2. Select "Settings

Newer SIM Cards: Select Compatibility option and make sure "On" is selected

Older SIM Cards: After selecting Settings:

2. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

Bear in mind that if you have powered your telephone down, and have removed and reinstalled the battery, you will need to follow the programming steps outlined above, again.

When dialed directly, some Nokia and other phones can display message: "Call is not allowed" or "Call is barred". Just ignore this message and wait for the ring-back for 10 seconds or so.

There are two ways you can do this:

1. For eSIM World you can use the 1SIM eSIM app.
2. From your mobile go to ma.onesimcard.com. This provides the access to your free  OneSimCard mini account. Free means that there is no need to have the SIM balance or data package on the SIM to be able to access this page in over 110 countries. Log in to your account and activate a new data package.
   
   2. From any computer log in to your on-line account at OneSimCard.com to order a data package. 

Simply go onto your web account or eSIM app and purchase a new data package appropriate to your travel needs.

For Universal E, Expedition E, eSIM World E, eSIM Asiania, Plus, Europe & More, & Standard SIM Cards, the international SIM card phone number and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the phone, SMS sent from the phone or any Data Usage.

Personal Extra Numbers will stay active as long as they have been funded properly.

The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10 month period provided that at least $25 is added within 10 months after the last recharge.

If the balance expires, the service can still be used after a new recharge of the SIM card.

For DataMax Plastic & DataMax eSIM SIM Cards, the SIM card and account will expire if no outgoing usage is made for 12 months. The outgoing usage could be any of the following: Call made from the OneSIM VoIP App, SMS sent from the OneSim VoIP app or any Data Usage.

Personal Extra Numbers will stay active as long as they have been funded properly and the SIM hasn’t expired. If the SIM card expires, but then is restored ($10 Restoration Fee applies), the PEN will be re-attached to the SIM card, as long as the PEN hasn’t expired based on the time period for which the PEN was purchased.

The SIM card balance is valid for 10 months. The balance will continuously roll over to the next 10-month period provided that at least $25 is added within 10 months after the last recharge.

If the SIM card balance expires, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package. So, to keep the SIM active you need to either keep a balance on the SIM or an active data package.

An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.
