Do I need to have a OneSimCard SIM card installed in my phone to use OneSim VoIP?
No. OneSimCard SIM is not required to be installed in the phone for OneSim VoIP to be used. However, you do need to have OneSimCard account with a VoIP capable PEN.Can I call using OneSim VoIP from countries where OneSimCard does not offer roaming coverage?
Yes. You can call from absolutely anywhere as long as you have a good Wi-Fi connection.Can I use OneSim VoIP over the Internet Data offered by OneSimCard SIM? Will it save me anything?
In countries where the cost of using mobile Internet Data is below 20 c/MB, the cost of using SIM VoIP over the data is comparable or less than the actual calling rate from the country.
As a rule of thumb, the SIM VoIP will use 1MB /Min of talk time. So, if the cost of Data in the country is 10 c/MB, then 1 minute SIM VoIP call will cost you 12 cents /minute. You need to have a 3G connection in order for SIM VoIP to work this way.Â

How often do I need to recharge my OneSimCard account?
Your OneSimCard global SIM card and European phone number will never expire as long as you make at least one call every 18 months. If you fail to make or receive at least one call every 18 months, your OneSimCard global SIM card and European phone number will expire and you will not be entitled to a refund even if at the time of expiration your account had a positive balance.
However, the funds on the SIM card will expire 10 months from your last recharge and will not be refunded to you. The minimum recharge amount is $25. By simply recharging at least once every 10 months your balance will roll over. If your balance does expire, it will not be refunded to you but all you need to do to get the service working again is to log in and add funds to your SIM card. If you set up the automatic recharge, it will be canceled if you allow the funds to expire, so you will need to set automatic recharge up again once you recharge your balance.
Â
DataMax SIM card has different rules. There is no balance on the SIM, so the balance will not expire. The SIM will expire 1 year after the purchase if either not renewed for one year for $10 or 7 days after the active data package has expired.
Is there a monthly or 30-day credit card spending limit for OneSimCard service?
To reduce fraud, there is 30-day credit card spending limit set for each individual account. You will only be able to charge up to a certain amount during any 30-day period. You can see your current limit by logging in to your OneSimCard account and going to the Purchase History menu. There, you will find a Credit Card Authorization form available for download. If you would like to increase your monthly credit card spending limit, please download the Authorization form and submit it back to OneSimCard as instructed on the form.
We strongly suggest that you set your monthly credit card limit before going overseas as dealing with the form on the road can be much more difficult.Â
