Are there any discount call (voice) plans available for Europe or other countries?
Yes, discount calling plans are available on select sim cards.
"Discount A" Voice Calls Plan
You can subscribe to the Discount Call Plan A for Europe (see country list below) and Turkey for just $3.99! Subscription is good for 30 days and will not automatically renew. This plan is available on the Plus and Universal SIM cards.
Once the discount plan is activated, you will be able to make calls from the countries below for only $0.15/min starting with the second minute! The first minute will be charged at the regular outgoing call rate:
Aland Islands, Austria, Azores, Belgium, Bulgaria, Canary Islands, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Jersey, Latvia, Lithuania, Madeira, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Svalbard, Sweden, Turkey and United Kingdom.

How can I dial '+' on my phone when making call?
Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.
You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.
Here are few known ways:
Â
I have an Apple iPhone. When I dial following your instructions it does not work. What's wrong?
 1. Locate OneSimCard Menu.
 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu
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.
The  eSIM World, eSIM Asiania, OneSimCard Europe & More and Universal SIM cards do not use the callback to make an outgoing call in over 70 countries.
Currently, the mobile application to remove the callback on other SIM cards is not available.
How should I send an SMSÂ to get charged only 15 cents per text message?
There are two ways for SMS message to be sent:
Bear in mind that sending SMS messages to the abbreviated special SMS destinations like voting, music downloads, etc. will cost you $9.00 per message.
Â
This does not apply to DataMax SIM cards.
How do I prevent the service from expiring?
The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 12 months.
However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.
NOTE: For DataMax Plastic & DataMax eSIM SIM cards, if the SIM card has no balance, 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.
Â
An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.
Â
I used a large amount of data  even though I barely used data, what happened?
Each mobile data session is charged for a minimum of 10kB usage. Even if you check just one 3k email you will be charged for 10kB of usage. In some countries this can be over 30¢ per session, however in Europe and elsewhere it can be as little as 1¢. Check all rates.
 Â
Each mobile data session is charged for a minimum of 100kB usage. Even if you check just one 3k email you will be charged for 100kB of usage.
Please note: Some phones, like iPhones, Androids, and other smartphones, can access data without you even knowing it if you have data enabled. We strongly recommend checking the settings on your phone and disable mobile data roaming if you will not be needing data service. By default, all SIM cards are pre-programmed with data service enabled, once you activate your data package.
