About mobile data roaming options for your iPhone and iPad

Turn Data Roaming on or off, prepare for international trips and more.

Turn off Data Roaming or prepare for a trip

Do you need to avoid roaming charges because you’ve arrived at your destination without an international data plan? Turn off Mobile Data and Data Roaming. 1,2 Open Settings and tap Mobile Data, Cellular or Cellular Data. Turn off Mobile Data, then tap Mobile Data Options and turn off Data Roaming.

Are you still planning your trip? Here are three ways to prepare:

Shop roaming plans with your network provider

Before you go: to avoid fees and higher rates, call your network provider or visit online to shop international roaming plans.

After arrival: open Settings. Tap Mobile Data, Cellular or Cellular Data. Then tap Mobile Data Options and turn on Data Roaming and other settings suggested by your network provider.

Shop roaming plans with eSIM and Apple SIM

Before you go: if you have an iPad with an eSIM or Apple SIM, you can browse mobile data plans from selected network providers in more than 90 countries, regions and territories.

After arrival: go to Settings > Mobile Data and buy a roaming plan that fits your needs.

Buy or rent local SIM cards

Before you go: you can usually 3 buy or rent a SIM card for a specific country or region. Find out more from travel guides and websites related to the country or region.

After arrival: Replace your current iPhone SIM card or iPad SIM card with the new one. You’ll need the original when you return home, so put it in a safe place.

1. When you turn off Mobile Data and Data Roaming, the mobile-data icon shouldn’t appear in the status bar. Find out more about mobile data settings and usage.
2. Apple Watch Series 3 (GPS + Cellular) and Apple Watch Series 4 don’t support data roaming. While using data roaming on your iPhone, your Apple Watch Series 3 (GPS + Cellular) or Apple Watch Series 4 will only be able to use Wi-Fi or your iPhone mobile data connection.
3. To use purchased or rented SIM cards, you’ll need an iPad (Wi-Fi + Cellular), unlocked iPhone or SIM-free iPhone.

Check your data usage

If you exceed the data-usage limits of your international data plan, you may run out of data or notice slower network speeds. To check data usage, open Settings and tap Mobile Data, Cellular or Cellular Data. Then look under the Mobile Data heading.

Get help when you have roaming issues during international travel

1. Turn on Airplane Mode for about 30 seconds. Then turn it off again and let your iPhone select the best network automatically.
2. If you see No Service in the status bar of your iPhone, open Settings and tap Mobile Data, Cellular or Cellular Data. Tap Mobile Data Options and make sure Data Roaming is turned on. Then, to check that international roaming is turned on for your account, contact your network provider.
3. If the date and time are wrong after you’ve arrived, go to Settings > General > Date & Time. Make sure Set Automatically is turned on.

Still need help? If so, here’s what to do:

1. Go to Settings > Mobile Data > Mobile Network and turn off Automatic. Wait until available networks appear, which may take two minutes.
2. Tap the network provider you want.
3. Go back to the main Settings screen and wait for your iPhone or iPad to connect to the network.
4. If you still need help, try a different SIM card or contact your network provider for more information.

Using Dual SIM with an eSIM

An eSIM is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM. With iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, and iPhone 13 mini, you can use Dual SIM with either two active eSIMs or a nano-SIM and an eSIM. iPhone 12 models, iPhone 11 models, iPhone XS, iPhone XS Max, and iPhone XR, feature Dual SIM with a nano-SIM and an eSIM. 1

How can you use Dual SIM?

• Use one number for business and another number for personal calls.
• Add a local data plan when you travel outside of the country or region.
• Have separate voice and data plans.

With iOS 13 and later, both of your phone numbers can make and receive voice and FaceTime calls and send and receive messages using iMessage, SMS, and MMS. 2 Your iPhone can use one cellular data network at a time.

If you want to use 5G with Dual SIM on iPhone 12, iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max, make sure that you have iOS 14.5 or later.

What you need

• An iPhone XS, iPhone XS Max, iPhone XR, or later with iOS 12.1 or later
• A wireless carrier that supports eSIM

To use two different carriers, your iPhone must be unlocked. Otherwise, both plans must be from the same carrier. If a CDMA carrier provides your first SIM, your second SIM won’t support CDMA. Contact your carrier for more information.

If you have an enterprise or corporate cellular service plan, check with your company administrator to see if they support this feature.

Set up your cellular plan with eSIM

On iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, and iPhone 13 mini, you can use two eSIMs for two or more cellular plans—two active at the same time—or a physical nano-SIM for a cellular plan and an eSIM for one or more other cellular plans.

On iPhone 12 models, iPhone 11 models, iPhone XS, iPhone XS Max, and iPhone XR, you can use a physical nano-SIM for a cellular plan and an eSIM for one or more other cellular plans. If you don’t have a nano-SIM and your carrier supports it, an eSIM can serve as your only cellular plan. The eSIM provided by your carrier is stored digitally in your iPhone.

You can store more than one eSIM in your iPhone, but you can use only one at a time. To switch eSIMs, tap Settings, tap either Cellular or Mobile Data, and then tap the plan you want to use. Then tap Turn On This Line.

Label your plans

After your second plan is activated, label your plans. For example, you can label one plan Business and the other plan Personal.

You’ll use these labels when you choose which phone number to use for making or receiving calls and messages, to designate a number for cellular data, and to assign a number to your contacts so you know which number you will use.

If you change your mind later, you can change your labels by going to Settings, tapping either Cellular or Mobile Data, and then tapping the number whose label you want to change. Then tap Cellular Plan Label and select a new label or enter a custom label.

Set your default number

Choose a number to use when you call or send a message to someone who isn’t in your Contacts app. With iOS 13 and later, choose which cellular plans you want to use for iMessage and FaceTime. With iOS 13 and later, you can choose either or both numbers.

On this screen, choose a number to be your default, or you can choose which number is to be used only for cellular data. Your other number will be your default. If you want your iPhone to use cellular data from both plans, depending on coverage and availability, turn on Allow Cellular Data Switching.

Use two phone numbers for calls, messages, and data

Now that your iPhone is set up with two phone numbers, here’s how to use them.

Let your iPhone remember which number to use

When you call one of your contacts, you don’t need to choose which number to use every time. By default, your iPhone uses the same number that you used the last time you called that contact. If you haven’t called that contact, your iPhone uses your default number. You can also specify which number to use for your calls with a contact. Follow these steps:

1. Tap the contact.
2. Tap Preferred Cellular Plan.
3. Tap the number you want to use with that contact.

Make and receive calls

You can make and receive phone calls with either phone number.

With iOS 13 and later, when you’re on a call, if the carrier for your other phone number supports Wi-Fi calling, you can answer incoming calls on your other number. When you’re on a call using a line that isn’t your designated line for cellular data, you need to turn on Allow Cellular Data Switching to receive calls from your other line. If you ignore the call and you have voicemail set up with your carrier, you’ll get a missed-call notification and the call will go to voicemail. Check with your carrier for Wi-Fi calling availability and find out whether additional fees or data usage applies from your data provider.

If you’re on a call and your other line shows No Service, either your carrier doesn’t support Wi-Fi calling or you don’t have Wi-Fi calling turned on. 3 It could also mean Allow Cellular Data Switching is not turned on. When you’re on a call, an incoming call on your other phone number will go to voicemail if you set up voicemail with your carrier. 4 However, you won’t get a missed-call notification from your secondary number. Call Waiting works for incoming calls on the same phone number. To avoid missing an important call, you can turn on call forwarding and forward all calls from one number to the other. Check with your carrier for availability and to find out whether additional fees apply.

Ratings and Reviews

Leider fehlen viele Pro Features

Ich benutze diese App schon länger auf meinem iPhone Xs und sie bietet beim nutzen von nur einer SIM Karte viele gute Funktionen und eine schöne Übersicht als Widget. Praktischerweise wird auch eine sSIM erkannt. Beim Nutzen einer Vodafone SIM mit GigaDepot wird sogar korrekt das zusammengerechnete gesamte Volumen angezeigt, sehr schön. Leider fehlt jedoch nach wie vor die Option sich das Datenvolumen von zwei oder mehr Tarifen anzuzeigen zu lassen was im dual SIM betrieb mit einer oder mehreren eSIM‘s wirklich Sinn machen würde. Zudem werden die Daten welche über eine Gigakombi Unlimited Flat laufen nicht erkannt, die Flat selbst auch nicht. Nur das Standard Volumen welches dann z.B. im EU Ausland zur Verfügung stände da dort die Flat nicht greift wird angezeigt. So verändert sich das angezeigte Volumen in diesem Fall nie, außer es wird eben im EU Ausland Roaming betrieben. Wünschenswert wäre auch, dass im EU Ausland das für den Vodafone Pass verfügbare Streaming Volumen separat angezeigt wird oder zumindest mit auf das Datenvolumen angerechnet wird. Echt informativ wäre noch eine Anzeige im Widget, dass den aktuellen up und down traffic anzeiget. Aktuell funktioniert die App noch nicht auf dem iPad Pro 2021 da die Aktualisierung immer fehlschlägt.

Für die Umsetzung von Pro Features wären bestimmt viele Power-User bereit sogar einen kleinen in-App Kauf zu tätigen da es dann schlicht die beste App auf dem Markt wäre.

Unterstützung weiterer Anbieter!

Die App arbeitet zuverlässig und bietet ein nettes Widget, dass zugleich minimalistisch und umfangreich in Erscheinung tritt. Zwei Punkte wären jedoch verbesserungswürdig. In Punkto Genauigkeit bei der Datenmessung anhand des Systems sind die Werte recht variabel. Die App misst immer weniger Verbrauch als es iOS und der eigentliche Anbieter machen. Möchte man die Anbieter spezifischen Werte in die App integrieren , ist die Auswahl an Anbietern sehr klein, gerade bei der momentanen Vielfalt an Drittanbietern. Gut möglich dass die Integration vieler Anbieter Schwierigkeiten darstellt, jedoch wäre eine Erweiterung dieser Funktion eine große Errungenschaft für die App, die sonst kaum eine andere im Store bietet!

Funktioniert prima mit Telekom Prepaid

Hatte vorher andere Apps getestet, hatten aber alle Probleme mit dem 4 Wochen Intervall. Hier funktioniert alles tadellos.
