Turning roaming on or off the right way – how to stay fully in control of costs & connectivity on the go

Browsing the web abroad and making calls doesn't have to be a cost risk! Whether you want to turn roaming on or off on your phone, the right setting gives you more overview and control over your spending while travelling.

Modern eSIMs like BuddySIM can help you focus more on the travel experience itself:

• switch roaming on to stay reachable,
• or switch it off deliberately to avoid higher costs.

Below, you'll learn how to choose the right settings depending on your destination and why it's worth preparing in advance.

What does roaming actually mean – and why is it important for travellers?

Roaming is the feature that lets your smartphone automatically connect to the networks of foreign providers when it's outside your home mobile network. This keeps you reachable on the go and lets you use data connections abroad. Travellers in particular benefit from roaming to

• make spontaneous plans,
• use navigation,
• or stay in touch with loved ones.

But: While turning on roaming within the EU usually stays free thanks to the “Roam like at home” rule, additional charges can apply outside the EU.

A good strategy: Decide before your trip whether and when roaming makes sense – and check out eSIM options like BuddySIM for a clearer overview.

Step by step: how to enable or disable roaming on Android devices

Whether you have a Samsung, Google Pixel, or Xiaomi, the process for turning roaming on or off on your phone is similar across all Android devices. With just a few simple steps, you can adjust the settings.

With BuddySIM, the network switch happens automatically in over 190 countries, so in many cases you no longer need to change settings or swap SIM cards.

Android: turning roaming on

• Open Settings (the gear icon).
• Select Network & internet or Connections.
• Navigate to Mobile networks or Mobile network.
• Enable Data roaming (toggle turns blue): now you're online abroad straight away – if your plan and network allow it.

Tip: The labels may differ slightly depending on the manufacturer, but the process stays the same.

Android: turning roaming off (for maximum cost control)

• Repeat steps 1–3 as above.
• Disable Data roaming (toggle turns grey): no more mobile data traffic is allowed abroad.

Handy for dual SIM: If you use BuddySIM and your home SIM at the same time, for example, you can switch roaming on or off for each SIM separately, keeping cost control flexible.

Checklist: how to handle roaming safely on Android devices

• Check your plan details (does roaming apply in your destination?)
• Select the correct SIM card and adjust the settings
• Keep checking roaming – especially when crossing borders
• Disable automatic app updates to save data

Roaming on the iPhone: how to keep everything under control

Whether in the hustle and bustle of the city or on holiday: anyone who uses an iPhone can easily switch roaming on and off. This can help you keep a closer eye on costs abroad – and with eSIM products like BuddySIM, you can often make the relevant settings quickly.

iPhone: turning roaming on

• Open Settings.
• Select Mobile Data or Cellular.
• Tap Data Options.
• Enable Data Roaming (toggle turns green): your connection abroad is now active.

iPhone: turning roaming off

• Open Settings as above and go to Mobile Data.
• Select Data Options and set Data Roaming to grey (disabled). Your roaming is now switched off – ideal for the cost-conscious and for long-haul trips.

Checklist: your roaming safety on the iPhone

• Pre-booked? Check your plan and country coverage
• Disable automatic syncing (e.g. photos, apps)
• Is your eSIM correctly set up and activated?
• If you have network problems, briefly restart your device

Avoiding cost traps: EU roaming and non-EU roaming compared

Within the EU, “Roam like at home” applies: calling, browsing, and texting at your domestic rates. In other words, you simply keep using your plan, often even with eSIMs like BuddySIM.

Outside the EU, however, high additional costs can loom: here data is often billed per megabyte. That's why you should disable roaming before any non-EU trip or switch straight to transparent eSIM offers to avoid nasty surprises.

Tips & tricks: how to avoid roaming costs abroad

To keep your holiday or business trip worry-free, there are a few proven strategies against cost traps:

• Use secure Wi-Fi connections: Whether at the hotel, café, or airport – Wi-Fi saves your data allowance.
• Enable Wi-Fi calling: Many devices let you make calls and send messages directly over Wi-Fi – you'll find this in the settings.
• Use airplane mode cleverly: Put your phone in airplane mode briefly, then enable Wi-Fi separately – ideal for maximum control over charges.
• Prepaid eSIM with a fixed price: With BuddySIM, you book a data package in advance and use your data worldwide at a fixed price.

Cost-trap checklist for your time abroad

1. Activate a spending limit with your provider
2. Check manual network selection to keep costs more under control in some countries
3. Disable voicemail abroad to avoid unexpected extra costs
4. Contact support in an emergency, e.g. BuddySIM Support

First aid: what to do when roaming isn't working

Problems with your internet connection despite roaming? Don't panic! Take a structured approach:

• Check your APN settings: Are the access points for mobile internet correct? On Android, check under “Mobile networks”; on the iPhone, under “Mobile Data”.
• Restart your device: Often a simple restart is enough for your device to register correctly on the foreign network.
• Check your plan in your customer account: Is roaming activated for your destination country? Check the status in your account.
• Contact support: If you're stuck, a direct line to your provider helps – e.g. through BuddySIM Support.

Problem	Solution
No internet despite roaming	Check APN, restart device
High charges after the trip	Use a spending limit & prepaid eSIM
Network not found	Manually select another network, contact support
