91. How To Use Questions
    • How can I dial '+' on my phone when making call?

      Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.

      You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.

      Here are few known ways:

      • Bosch: Press and hold the star (*) key until the "+" sign appears.
      • Motorola: Press and hold the zero key until the "+" sign appears.
      • Nokia: Press the star (*) key twice in rapid succession.
      • Pocket PC: Pull up the keyboard, hit the <123> button in the top left corner, and select "+" from the resulting screen.
      • Samsung: Press and hold the zero key until the "+" sign appears.
      • Sony Ericsson: Press and hold the zero key until the "+" sign appears.
      • Treo 270: Press the blue button and then the "G" key.

       

92. Troubleshooting Questions
    • I have a Samsung phone. When I dial following your instructions it does not work. What's wrong?

      Some phones such as Samsung and some other brands require dialing a specific prefix 146 in front of the dialed string when used with a OneSimCard.

      For example, calling to USA: Dial *146*0016175551212# and press the TALK (or SEND) button
      * is a star character located on the keypad 
      • 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* can be used from any phone. However, most phones do not require it.

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

      How to activate compatibility mode:

        1. Locate and Open "OneSimCard" Menu. ( It could  be displayed as STK Menu)

              2. Select "Settings"

        Newer SIM Cards: Select "Compatibility" and make sure "On" is selected
        Older SIM Cards: After selecting Settings:
        1. Agree with message by pressing "Yes"
        2. 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.

      93. Ordering Questions
        • How do I order Discount Call, Text and Data plans?

          You can order discount Call, Text and Data packages from your OneSimCard web account after you have received and activated your OneSimCard. 

          NOTE: for DataMax and DataMax eSIM, there are no call or text messaging discount package, since these are already deeply discounted through the 1SIM VoIP App.

          To order a discount package for your SIM card, follow these steps:

          1. Log into your account at OneSimCard.com
          2. Click on the My SIM Cards menu links
          3. If you have more than one SIM card, make sure the SIM Card you’d like to activate a discount package for is selected
          4. Navigate to the Discount Service Plans section and select a discount package you would like to activate
          5. Click Activate Now to activate the selected package immediately or Activate Later to schedule the activation on a particular date.

           

          Future data plan activation:

          a. You can set up the maximum number of times data packages to be activated automatically when the package is used up or expired.

          b. You can set the date after which no packages will be activated, so when your travel is over no data packages will be activated and no charges will follow.

          Note: eSIM World data plan activation may vary from regular Universal or Expedition SIM cards. Please follow directions on the account page.

          To learn more about the availability of discount packages for different SIM cards and countries, please visit the Rates & Coverage page.

           

      94. Troubleshooting Questions
        • When I try to make a call, I get a message 'Call is modified and cannot be made'. What does that mean?

          Some phone models do not allow direct dialing with older OneSimCard SIMs sold before January 1, 2017.

          To get around this problem, you should try either of these methods:

          • Locate the OneSimCard menu on your phone. (Some phones have it in Applications.)
            Make a call using menu 'Call'.
          • You can also make a call by dialing directly *146*00 Country Code Number#
            For example, to make a call to the USA, you would dial *146*0018574440686# (do not forget to hit pound at the end of the number)

          * is a star character located on the keypad

          Other examples of how to use the *146* dialing prefix if necessary:

          • 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 (it is a star character located on the keypad)
          • 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 prefix *146* and # at the end can be used from any phone. However, newer OneSimCard SIM do not require it and you should be able to dial codes directly, 091, 094, 095, 099 or 098XXXX*XX Talk.

          If you have an older SIM and the dialing does not work without entering *146*, please follow these simple instructions to remove the need to dial *146*:

          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 and it looks like one of the apps

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

          Newer SIM Cards: Select Compatibility option and make sure "On" is selected

          Older SIM Cards: After selecting Settings:

          1. Agree with message by pressing "Yes"
          2. 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.

          When dialed directly, some Nokia and other phones can display message: "Call is not allowed" or "Call is barred". Just ignore this message and wait for the ring-back for 10 seconds or so.


      95. Troubleshooting Questions
        • I am traveling in Saudi Arabia and can receive calls, but I can't make an outgoing call. What should I do?

          Local carriers in Saudi Arabia sometimes block standard OneSimCard outgoing calls. If this happens you need to either (a) enter a compatibility code into the settings of your phone or (b) initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

          How To Activate Compatibility Mode:

          1. Open "OneSimCard" menu
          2. Select "Settings"
          3. Agree with message by pressing "Yes"
          4. Dial digits "802" and select "OK" (screen will show message "output channel is SMS")

          Bear in mind that if you have powered your telephone down and removed and reinstalled the battery, you will need to follow the programming steps outlined above again.

          How To Deactivate Compatibility Mode:

          1. Open "OneSimCard" menu
          2. Select "Settings"
          3. Agree with message by pressing "Yes"
          4. Dial digits "801" and select "OK" (screen will show message "output channel is USSD")

          How To Dial Without Activating Compatibility Mode:

          Initiate your call by sending an SMS message from the regular SMS menu (not the OneSimCard menu) of your phone.

          To: 9146
          Message: 00 + Country Code + Number + 
          * is a star character located on the keypad

          For example, to call from Saudi Arabia to Boston USA you should go to the SMS menu of the phone and send a message:

          To: 9146
          Message: 0018574440686
          After your SMS is sent wait 3-10 seconds. You will get a callback as usual and your call will be connected to the destination number.

          Note 1: You can't send this SMS from the SMS OneSimCard menu of the phone.

          Note 2: If you see on the screen that the message has not been sent, make sure that SMS settings of your phone is complete and the SMS Center number is set to: +3725099000

           

          There are no special instructions to receive calls in these countries.

      96. How To Use Questions
        • How do I set up SMS text messaging on my 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:

          Problem with Sending SMS:

          • Incorrect SMSC number (SMS Service Center Address) in handset settings.

          SMSC number should be set as follows:

           

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

          a. China:  +85290296747

           

          2. For the Expedition (former 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 phone. 

          To change the SMSC on Iphone dial: 

          Plus and Standard SIMs: **5005*7672*+3725099000# for all countries except China and **5005*7672*+85290296747# if in China.

          Expedition (formerly Data & Roam) and Europe & More SIMs in any country: **5005*7672*+37256100041#

           

          If your phone requires the name of Message Center Name enter: SMSC
          SMS lifetime is short - must be at least 2 hours or set to Maximum settings.
          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.
      97. How To Use Questions

      98. Troubleshooting Questions
        • I have an iPhone and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

          This is a known issue with Apple's Facetime and iMessage applications on Apple iPhone  devices. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone applications and how they communicate should be directed to Apple Support.
          You can learn more on the Apple Support web site:
          https://discussions.apple.com/thread/5968824
      99. Troubleshooting Questions
        • I just arrived in a foreign country and my phone is not working, what should I do?

          If you left your phone on during your flight or cruise then you should fully power down and restart your phone. Once your phone powers back on it should automatically select an available roaming network.

          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.
          In some countries like in USA turning off 3G mode of the phone will make it quicker for the phone to register on the network.
      100. Troubleshooting Questions
        • I can't send SMS from my iPhone

          There is a known bug with iPhone phone book. If you are trying to text to a contact that is entered in the phone book, and the contact is not entered in proper international number format, the SMS will not go through even if you just enter the number in the SMS menu directly and properly. 
          Please edit the record in the phone book to be +CountryCode_Number. It needs to have the + character in front, which is an equivalent of 00.

          You will also need to delete all recent attempts to send SMS to this number from the Messaging menu. It should be no conversation or attempts to send SMS left in the phone to this number.


          We understand that this is very frustrating, but do not know why Apple will not fix it. This problem affects only Apple phones.

          Example: for US Number 1-617-600-8250 you should have entered in the address book: +16176008250
          Delete existing text conversation after fixing the phone book record. 
          You can always test your SMS by sending SMS to OneSimCard Support number +16176008250 from your OneSimCard phone. This will create an automated ticket in the system and you will know if the message was delivered or not. You will be charged regular SMS rate for this message.
