Cellular & SIM settings help you control the cellular settings for your phone—including your cellular data connection. You shouldn't need to change anything if your connection is working the way you like. But if you're having cellular connection problems, changing one or more settings below may help.

To open Cellular & SIM settings, from Start , swipe over to the All apps list, and then select Settings  > Network & wireless > Cellular & SIM.

Setting Does this

Data connection

Turns your cellular data connection off and on. You might turn off your connection for different reasons—for example, to reduce your data usage if you're not on an unlimited data plan, or to make your battery last a little longer.

If your connection is turned off, you can still make and receive phone calls and send and receive text messages. But you can't do things like browse the web, search online, receive or send email, or get updated info for apps unless you're connected to a Wi‑Fi network.

Another way to turn your cellular data connection on or off is to swipe down from the top of your screen, then select Expand > Cellular data.

Cellular connection name

Shows the name of the cellular connection you're using. Select SIM settings under the cellular connection name to change the settings for your cellular connection.

Use this SIM for cellular data

Determines which SIM is used for your cellular data connection. You can choose the SIM you want to use for cellular data to help control your data costs. For example, you might choose one SIM instead of the other because it costs less for data. This setting only appears on dual SIM Windows phones.

Data roaming options

Determines if your data connection stays on when the phone is outside your mobile operator's network in a roaming area. Leaving it set to Don't roam can help prevent data roaming charges.

If you do allow roaming, you can use cellular data when your phone is in a roaming area. Depending on your phone plan, you might pay more for data you use when roaming. Some mobile operators let you specify what kind of data roaming you want to allow—Domestic or Domestic + international roaming.

On a dual SIM phone, you can set the roaming options for each SIM.

Voice roaming options

Determines if you can make calls and send text messages when your phone is outside your mobile operator's network. Leaving it set to Don't roam can help prevent some voice roaming charges. When it's set to this, you can't make calls or send text messages when your phone is in a roaming area, but you can still get calls and receive text messages. Check your phone plan for details about how and when additional charges might be incurred.

If you do allow roaming, you can make calls and send text messages outside your mobile operator's network. Depending on your phone plan, you might pay more for these calls and text messages. Some mobile operators let you choose which kind of roaming you want to allow—Domestic or Domestic + international roaming.

Phone number

Displays your phone number.

To get to this setting, in Cellular & SIM settings, select SIM settings. On a dual SIM phone, select SIM 1 settings or SIM 2 settings.

SIM name

Type a name for your SIM to give it a friendly name that you'll recognize.

For dual SIM phones, this helps you tell your SIMs apart, so you know which SIM you're using for your cellular data connection and when calling or texting. The SIM names will appear in different places on your phone, such as on your Phone tiles, Messaging tiles, for your SIM contacts, and in Cellular & SIM settings.

To change the name of your SIM, in Cellular & SIM settings, select SIM settings > SIM name, type a new name, and then select Save. On a dual SIM phone, select SIM 1 settings or SIM 2 settings to name each one.

Highest connection speed

Determines the highest connection speed your phone can use. If you choose the highest one, your phone will use the highest cellular connection speed that's available in the current area. But if there's low signal strength, searching for or trying to stay connected to a faster connection can take extra battery power.

When you choose a lower connection speed, your phone can connect to a slower cellular network that may have a stronger signal. This can also save battery power.

To get to this setting, in Cellular & SIM settings, select SIM settings > Highest connection speed. On a dual SIM phone, select SIM 1 settings or SIM 2 settings > Highest connection speed.

Network selection

Lets you view a list of available networks in your current area and then try to connect to one. The default setting is Automatic.

If you turn on your phone and see a message that the selected network isn't available, you can select Search for networks, and then select another cellular network.

To get to this setting, in Cellular & SIM settings, select SIM settings. On a dual SIM phone, select SIM 1 settings or SIM 2 settings.

Active network

Displays the name of the cellular network that you're using.

To get to this setting, in Cellular & SIM settings, select SIM settings. On a dual SIM phone, select SIM 1 settings or SIM 2 settings.

Update settings

To get to this setting, in Cellular & SIM settings, select SIM settings > IMS roaming options.

Calling preference

Determines which connection—cellular or Wi‑Fi—is preferred for making and receiving phone calls. If you choose Wi‑Fi only, you'll only be able to make and receive calls when connected to Wi‑Fi.

Add an Internet APN

The Internet access point name (APN) is the address your phone uses to connect to the Internet when using your cellular data connection. Usually, the Internet APN is set automatically.

If your cellular data connection isn't working, try typing a new Internet APN. For example, you might enter a new Internet APN if you can make calls and text message, but can't browse the web on your phone. The Internet APN settings you should enter are based on your location and mobile operator. If you can connect to a Wi‑Fi network on your phone or have your PC nearby, try searching online to find the Internet APN settings for your mobile operator.

To add an Internet APN:

Use SIM PIN

Determines if you want to use a PIN for the SIM in your phone to help prevent other people from using the cellular data connection when they're not authorized. After you set up your SIM PIN, you'll be prompted to type the SIM PIN when you start your phone.

The first time you're prompted for a SIM PIN, type the default SIM PIN. If you don't know the default SIM PIN, visit your mobile operator's website to see if they list it there. You'll need to restart your phone for it to be locked with a SIM PIN.

If you've already set up a PIN for the SIM, type your SIM PIN when prompted, and then select OK.

To go to this setting, in Cellular & SIM settings, select SIM settings > Use SIM PIN under the Security section. On a dual SIM phone, select SIM 1 settings or SIM 2 settings> Use SIM PIN.

Change SIM PIN

This appears if you're using a SIM PIN. To change your SIM PIN, select Change SIM PIN, type your current SIM PIN in the SIM PIN box, type a new SIM PIN in the New SIM PIN box, type the same new SIM PIN in the Confirm new SIM PIN box, and then select OK.

To go to this setting, in Cellular & SIM settings, select SIM settings > Change SIM PIN under the Security section. On a dual SIM phone, select SIM 1 settings or SIM 2 settings > Change SIM PIN.

Remove SIM PIN

This appears if you're using a SIM PIN. If you decide you don't want to use a SIM PIN anymore, select Remove SIM PIN, type your current SIM PIN, and then select OK.

To go to this setting, in Cellular & SIM settings, select SIM settings > Remove SIM PIN under the Security section. On a dual SIM phone, select SIM 1 settings or SIM 2 settings > Remove SIM PIN.

Unblock SIM PIN

This appears if you're using a SIM PIN and the incorrect PIN has been entered three times. When this happens, the SIM PIN will be blocked and can't be used until you unblock it. To unblock it, first contact your mobile operator for the PIN Unblocking Key (PUK). After that, select Unblock SIM PIN, and then type the PUK code. If an incorrect PUK code is entered too many times, your SIM card will be permanently blocked, and you'll need to get a new SIM card from your mobile operator.

To go to this setting, in Cellular & SIM settings, select SIM settings > Unblock SIM PIN under the Security section. On a dual SIM phone, select SIM 1 settings or SIM 2 settings (depending on the SIM you want to unblock) > Unblock SIM PIN.
