We are here to help you get answers to your questions about OneSimCard phones and services.
What Is the Difference Between "Direct Dial" and "Callback Dial" calling?
Direct Dial calling allows the caller to enter the international call prefix, country calling code and telephone number and then be directly connected to the person they are calling. This is how you dial when using your regular mobile service. Direct Dial Calling is standard on the OneSimCard Europe & More, OneSimCard Universal and eSIM.
Callback calling also allows the caller to enter the international call prefix, country calling code and telephone number. After the called number is entered, the user immediately receives an incoming call connecting the user to person called. Callback is very simple to use and allows for low cost calling on the OneSimCard Plus and OneSimCard Expedition (formerly Data & Roam). Callback does not increase the connection time. It is the same as with Direct Dial.
What is 1SIM FUND?
The OneSimCard Money Fund allows you to pay for OneSimCard services by means other than credit cards and also by Visa and Master Cards enrolled in the credit card security programs:
Â
Once you deposit money into your OneSimCard Money Fund through one of above methods, you can use this fund to recharge your SIM(s), order a second number, or make any other payment for orders placed at OneSimCard.com.
OneSimCard Money Fund additions are non-refundable. However, the money you put into the fund does not expire. There are no fees applied to the fund maintenance either.
Example 1
You are in Kenya and can't pay using a credit card. You would like to purchase a OneSimCard SIM for $39.95, and also be able to add airtime (recharge) later. You will also need to pay for shipping.
First step - you need to add funds to your OneSimCard Money Fund. It's up to you what amount you would like to send us, but it should be large enough to cover your purchases. Let's say you posted $200.00 to your OneSimCard Money Fund.
Once the money is received, we will send you a confirmation email. Then you can log in to your OneSimCard.com account and place your order. It will be instantly processed and the money will be deducted from your OneSimCard Money Fund account.
Example 2
You have 3 SIM cards and 3 personal second numbers.
You want to set up auto-recharge for SIM1 and SIM2 in $25 increments and the third one in $50 increments. You also want to extend (recharge) your Second Numbers every month.
Let's say you put $500 into your OneSimCard Money Fund account. Now you can set up $25 auto-recharges on your 2 SIMs and $50 auto-recharge for your 3rd SIM, as well as and automatic extension of your second number.
This option allows many users around the word to take advantage of OneSimCard.com services without using a credit card.
Example 3
You use your credit card account to add money to the 1SIMCard Money Fund. The transaction from a credit cardl is instant. Funds will be instantly added to your 1SIM Card Money Fund, and then you can use the Money Fund to make any purchase at OneSimCard.com.

How do I know if USA, Canada or UK Mobile PEN I order is capable of receiving SMS?
To see if your PEN is capable of receiving SMS, please log in to your on-line account at www.OneSimCard.com. In the Recharge Menu next to the PEN you will see if it is SMS capable or not. You can also see there if this PEN could be used for VOIP or not.Can I disable per MB/Pay-As-You-Go data usage for DataMax SIM cards
Yes you can. On your online account, in the "My SIM cards" menu, you will see a section labeled "Select SIM Card." In that section there is a line labeled "Use w/o Plan." If you do not want to use data on a per MB/Pay-As-You-Go basis, and only consume data with a data plan, set this to "Off."When I send an SMS text message I am sometimes charged for multiple outgoing text messages, what's wrong?
This means that your SMS text message has been split up into multiple messages because it contains too many characters.I just activated my SIM card and can't make a successful test call. What's wrong?
If you just activated your SIM card and can not make a test call by following the instructions in the user manual, you will likely just need to power off the phone and power it back on again. The phone should automatically re-register with one of our partner networks. Remember, if you answer the test call when it rings you will be charged for the call.© 2006-2025 Belmont Telecom Inc., DBA OneSimCard.com. All rights reserved
