With the exception of UK Mobile numbers, all PENs are not mobile numbers. These numbers are capable of receiving and forwarding calls and in some countries like US, CANADA and UK they are capable of receiving texts. When making outgoing calls using PENs, the Caller ID can be set to show either this PEN or the Main SIM card number. This option is available in the online account.

OneSimCard international mobile service does not require dialing any access numbers when calling from international locations, you simply dial as you normally would when you're abroad. However, when somebody is calling to your OneSimCard phone there is an option for them to call you through a Toll Free or local number rather than dialing your European mobile number directly, which could be expensive for them. This call will instead be charged to your OneSimCard account at an additional 20c/min to the incoming rate in the country where you are receiving the call.

When someone calls you through a Common Access Number they receive a prompt where they then enter your primary European number starting with 372 to reach you. For a direct connection, we recommend adding a Personal Extra Number (PEN) instead.

At this time we have Toll Free and/or Local Common Access Numbers in the following countries:

• Argentina
• Australia
• Austria

You can find these numbers in the User Guide or while logged in to your OneSimCard web account portal.

There are no monthly fees or connection charges for using OneSimCard international cell phone service.

If you order an optional Personal Extra Number (PEN), there is a small periodic fee to keep the PEN active based on how you choose to be billed (from $1.67 per month). There is also an additional charge to receive a call through any Extra Number. View our Rates & Coverage page and click on any country to view our available Extra Numbers and associated costs.

The SMS Verification PEN is the only PEN that can be used without a SIM card. Thus, it can have its own balance, which follows these rules:

1. If the SMS Verification PEN is used without a SIM card, the PEN's balance will be valid for 12 months. To maintain it the minimum recharge amount of only $10 USD per year is required.
2. If the PEN has a SIM card assigned to it, the SIM card balance rules will apply. To maintain the balance both for the SIM and all PENs assigned to it $25 USD min recharge will be required every 10 months.

New SIM card orders with PENs

Your monthly, quarterly, bi-annual or annual subscription to a Personal Extra Number starts the moment your order has been shipped. If you do not need your Extra Number to be active right away, you can always wait and order an Extra Number later at any time by logging into your account.

eSIM orders on onesimcard.com do not require shipping.

PENs added to existing SIM cards

These PENs subscriptions are activated right after the order has been processed. The activation is pretty much instant, unless your PEN order requires additional documents for verification. Please see the local number information page for the list of any additional document requirements by country.

Free Trial PENs

Many SIM cards come with Free Trial PENs that are inactive by default. You can activate Free trial PENs at any time from your account.

BANK SMS Verification PEN

The SMS Verification PEN is the only PEN that can be used without a SIM card. These PENs are activated instantly if ordered on their own or added to an existing active SIM card.

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 30c per session, however in Europe and elsewhere it can be as little as 1c. Check all rates.

Please note: Some phones, like iPhones 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 or disabling GPRS from your OneSimCard account if you will not be needing data service. By default, all SIM cards are pre-programmed with GPRS data service disabled.
