FREQUENTLY ASKED QUESTIONS

Of course you can! Simply send and receive SMS texts according to your phone's user manual or from the OneSimCard Menu. Receiving SMS is always free. Sending an SMS (text message) is $0.15 - $1.50 depending on the country.

SMS messages sent to a OneSimCard phone should always be sent to the main OneSimCard mobile number rather than to an optional Extra Number, with the exception of new SMS enabled numbers in USA, Canada and UK Mobile available since Jun 3rd, 2014. When replying from OneSimCard phone to the SMS received on USA or Canada SMS capable PEN using Europe & More sim or the Expedition SIM, the main number of the SIM that starts with 372 will be displayed on the text receiver phone. With the Universal SIM, you can select what caller ID will be shown on the SMS receiving party phone.

You can also send SMS messages from OneSim VOIP app at much lower rates. Note: for Physical 3-in-1 Datamax and Damax eSIM all SMS messages MUST be sent through the OneSim VoIP App with PEN.

You can also send a free SMS message to any OneSimCard customer from our web site or by sending email to 372XXXXXXXX@sms.onesimcard.com, where 372XXXXXXXX is the OneSimCard primary mobile phone number. The maximum number of daily SMS sent to the SIM over email or web is 25.

Please bear in mind that message should be sent in English characters. In addition, it should not be longer than 160 characters including spaces.

These 2 options of sending SMS by email provide completely free way of communicating, as it is usually free for you to send the email and costs nothing for the OneSimCard customer to receive a text message.

For Universal, Expedition, and eSIM World SIM cards, many U.S. and Canadian carriers can charge more than $3/minute to connect to an Estonian mobile number, the primary mobile number for a OneSimCard global SIM card. Your SIM card includes a U.S. number which will be much less expensive for people to call.

Callers can also use one of the Common Access Numbers (CAN) that we provide to you free of charge in more than 10 countries. Your OneSimCard account will simply be charged an additional 20c/min to the incoming rate in the country you are in to receive those calls. There is also the option of ordering a dedicated Personal Extra Number (PEN) in Canada and many other countries that will forward all calls directly to your OneSimCard cell phone. You can see the list of countries where PENs are available here:

You can order a Personal Extra Number when placing your order or later at any time by logging in to your account. Visit our Rates & Coverage page and choose any country to view all rates.

If you would prefer for the caller to pay for calls made, we recommend they buy Peanuts Prepaid. Using this service would guarantee a connection to your OneSimCard mobile phone from the U.S and Canada for 20c/min and it is very easy to use without switching your LD carrier.

For Physical 3-in-1 DataMax and DataMax eSIM, if you chose to use SIM VOIP app, your friends and family will call the PEN number you are assigned, so in most cases, there will be no tariff for them to call you, and the cost to receive the call is only $0.01/Minute.

Some recent Android upgrades to versions 4.2.1 and 4.2.2 have a bug causing the OneSimCard Menu, labeled as SIM Toolkit, to be disabled.

If you do not see the SIM Toolkit app in your Android phone, please try doing the following:

Go to Settings>Security>Other Security Settings>Setup SIM Card Lock>Lock SIM Card. It will ask for the default SIM PIN. Enter 0000. Power off the phone and turn it back on. The SIM Toolkit app will then become available, though it might take 1-2 minutes for the phone to display it.

On Android version 5.1 go to Settings > SIM Cards > SIM Toolkit

Once you have access to the SIM Toolkit, select it, scroll down to Settings, enter 1101 and press confirm. Your phone will now be able to dial normally.

For eSIM cards, make certain that your eSIM is enabled.

 

Yes, you will need to activate the SIM card once the order is received.

All OneSimCard international SIM cards and international cell phones with SIM cards are shipped inactive to prevent theft and improve security. Only the person who placed the order for OneSimCard service can activate it.

Activation is very simple: When you receive the SIM, just log in to your account at www.OneSimCard.com and click the large Activate button you will see in the middle of the screen.

Retail Customers: If you purchased your SIM card through an online or brick-and-mortar retail store, you should have received activation instructions inside the product packaging. To activate retail SIM cards, go to www.OneSimCard.com/Retail enter your new OneSimCard international mobile number and fill out the form to register and activate the SIM card. You will be provided specific instructions on the registration page.

OneSimCard will work with almost any unlocked GSM tri-band or quad-band cell phone. A partial list of compatible cell phones that we have tested can be viewed here.

If you need to unlock the phone, we suggest contacting your carrier or phone manufacturer for unlocking information or services.

If your phone is not a quad-band phone, please make sure that the bands of your phone are those required in the country of your travel. You can look it up here.

If you are still unsure whether your cell phone is compatible, contact support or purchase an international cell phone and SIM card bundle from us, which all come preloaded with our international SIM card, $10 balance  and OneSimCard Apps Installed.

Sometimes when moving from the USA, Canada or Mexico to another country, the SIM card will need to be reset to properly register on a new country roaming network.
