FP3(+). Set up the SIM card(s)


Your Fairphone 3/Fairphone 3+ (FP3/FP3+) supports only nano-SIM card(s) (4FF), sized: 12.3 mm x 8.8 mm. You can use two nano-SIM cards.

We recommend using a new SIM card. The SIM card(s) do age like any other electronic circuit and might cause unnecessary issues to your phone. A good practice is to change your SIM card every 2 years. You can ask your network provider for a new one.

Like almost every Dual SIM device on the market, FP3/FP3+ implements the standard Dual SIM Dual Standby (DSDS). This means that both SIM cards are ready to be used at any time to receive or make phone calls. However, you can only use one of them at a time. Additionally, you will have to decide in advance your preferred SIM card to use for Cellular data.


Insert the SIM cards

To insert the nano-SIM card(s) into your FP3/FP3+, please, read the instruction below. You can also watch our short video tutorial for more information.

  1. Open the back of your phone.
  2. Take the battery out. Underneath, you'll see three icons outlined in white
    1. On top is the SD card slot 
    2. Below are the two nano-SIM card slots
  3. Insert your nano-SIM card(s) into the nano-SIM card(s) slot(s)
    Do not force a SIM card
    into the Micro SD card slot. You'll void the warranty!
    1. If you have only one SIM card, we advise you to insert it in Sim 1 slot.
    2. If you have two SIM cards, we advise you to put your main SIM card (the one you will be using the most for mobile data connection and calls) into the Sim 1 slot.
  4. Press all the way gently in until the nano-SIM card(s) click in place 
  5. Insert the battery again
  6. Put the back cover back on
  7. Press the Power button to restart your phone

To take out a nano-SIM card in your FP3/FP3+

Set your preferences

When you add or change the SIM cards, you will have to set your SIM cards preferences

  4. Enable or disable a SIM card by simply tapping on the Use SIM switch.
  5. Select your preferred SIM card for:
    1. Cellular data. Here you must choose. SIM card 1 is selected by default, but you can change it. Only one SIM card can use data at a time.
    2. Calls. Here you can pick a specific SIM card or decide to be asked every time you want to make a phone call
    3. SMS. Same as calls. You can pick a specific SIM card or decide to be asked every time you want to send a message.


Advanced data settings

The default settings are usually good for most users. Thus we recommend you skip this section if this is not necessary for you

Please, be aware that depending on how you set these settings, your apps will stop working. For example, it might happen that you will not get any more notifications from your favorite apps until you open them! Think of WhatsApp, Instagram, Email apps, etc.

If you are instead an advanced user, you can go to Settings  Network & Internet SIM Card  → scroll to the bottom → Advanced to adjust some more settings. Here you can:

  1. Turn Mobile data On or Off for a specific SIM card
  2. Set data warning (per cycle) for your cellular data. The phone will notify you when the threshold is reached
  3. Set data limit (per cycle) for your cellular data. The phone will deactivate mobile data when the threshold is reached.
  4. Manage the usage of Background data for a specific app. Here you can stop apps from synchronizing any data until you open them. This means you will have no notifications! 
  5. To restrict background data usage for all apps, go to Settings → Network & internet → Data Saver and set it to on.
  6. Enable or disable call enhancement features such as VoLTE and Wi-Fi Calling. The availability of these features depends on your region and network.


General recommendations

A data connection is at the core of all the functions of a modern smartphone. To avoid over-using your mobile data, we suggest you always connect to a Wi-Fi network when possible.
Additionally, to avoid bad surprises, you can contact the customers' service of your network provider and ask them to help you analyze your mobile data consumption and make sure to choose the best plan for your needs

Your FP3/FP3+ has plenty of power to accompany you for a full day of regular usage

To quickly enable or disable mobile data on your device:

  1. Swipe down from the top of your screen
  2. Tap on the Mobile data icon to turn mobile data On or Off
