OneSimCard SIM VoIP users with US and Canadian numbers may now send and receive text messages over the OneSim VoIP app on iPhone and Android. The cost to send or receive each message is $0.05. 

Note: SMS sent from VoIP app can only be sent to USA and Canadian numbers.

It's actually quite simple to rent a OneSimCard international cell phone phone bundle to use during your travels. Just tell us the date you need the phone and we'll ship a complete package directly to your door. Your package will include a mobile phone programmed with an international phone number, extra battery, charger, international travel plug adapter, holster, OneSimCard User Guide, $5 worth of initial airtime, and a US Mail return envelope. When you return from your trip, simply return the package in the envelope provided - just add postage.

Update: As of March 5, 2018, all rentals come with a prepaid USPS Priority Mail return label. Simply attach it to the provided return envelope with your rentals inside and drop it off at the nearest post office. It’s that easy!

When you tell us the country of your travel, we will select the SIM card type for you that offers the lowest calling rates in this country.

1. Activate your SIM card(s) (you should wait to activate until after you receive the package)
2. Once the SIM is activated, you can set up the PEN. You will see the link on the screen in the Recharge Menu. The PEN activation is done instantly. If you activate the Free US PEN, it will stay active for the duration of your travel. Alternatively, you can order a PEN in your local area or in another country if you require one. 

This answer applies to SIM cards purchased before January 1, 2017.

Some phones, such as Samsung, some Motorola, Android and Apple iPhones, require special dialing instructions or simple OneSimCard settings menu changes in order to make calls.

It is possible to make almost any phone entirely compatible, so you can call directly without using the OneSimCard menu or *146* by following these simple programming instructions below.

How to activate compatibility mode:

  1. Locate OneSimCard Menu.

 On iPhones it is called SIM Applications menu and is located under Settings- Phone menu

         On Androids it is called SIM Toolkit app or OneSimCard app and it looks like one of the apps.

2. Open "OneSimCard" menu ( SIM Applications, SIM Toolkit, STK)
3. Select "Settings

4. Agree with message by pressing "Yes"
5. Dial digits "1101" and select "OK" (Screen will show "CC OptionX: ON" message)

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.

If for any reason after entering compatibily code, you still do not get a ringback or you get the ringback the first time you make a call, but second time it would not work, please enter code 802 into the Service Code window instead of 1101 as provided above.

Please bear in mind that Android phones can use OneSimCard Direct App available free for download from Google Play.  Using this app takes care of the Android phones compatibility issues, allows to remove the callback ring (Android OS version 5 or below) and also will automatically correct mis-dialed phone calls in most cases. iPhone users can download OneSimCard Assist App from iTunes that will do the same, except for removing the ringback.

For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button

• To check your balance dial  *146*099# and press the TALK (or SEND) button
• To add funds dial *146*098XXXX*ZZ# and press the TALK (or SEND) button,
  where XXXX - 4 last digit of your credit card on file, ZZ - Recharge amount
• You need to press * on your phone in the above dialing sequences
• Activation of voice mail *146*091# and press the TALK (or SEND) button
• Deactivation of voice mail *146*090# and press the TALK (or SEND) button
• Check number of messages in Voice Mail *146*094# and press the TALK (or SEND) button
• To listen to voice mail *146*095# and press the TALK (or SEND) button

The sequence *146* and # at the end can be used from any phone. However, most phones do not require it.

We strongly recommend you to watch very short video tutorials that will help you to understand how to make calls, SMS and data on your OneSimCard Phone.

SMS messaging usually works without any additional setup of the phone.
In rare cases when there are issues sending or receiving text messages, please look at the following:

1. For Standard  and Plus OneSimCard SIM: +3725099000 for all countries except:

a. China:  +85290296747

2. For Data & Roam SIM as well as for Europe & More SIM: +37256100041

Special instructions for Apple Phones:

With Apple iPhones to check SMSC:

From the phone dialer Dial *#5005*7672# 

You will see the SMSC set currently on the the phone. 

To change the SMSC on Iphone dial: 

Plus and Standard SIMs: **5005*7672*+3725099000# outside of USA or Canada and and **5005*7672*+85290296747# if in China.

Try sending SMS from OneSimCard menu

 Problem with Receiving SMS:

• Receiving Handset does not have enough free memory for incoming SMS.
• Receiving Handset was turned off or out of the coverage area during SMS lifetime set on the sending phone - usually 2 hours.
• Sender's SMS provider does not have an agreement with the receiving network.
