The easiest way to test your roaming SIM is to insert the SIM card in a phone. Switch off Wi-Fi on the phone and then check that both mobile data and data roaming are switched on. Then open a website or an app that uses the internet to check whether you can get online. If […]
Roaming must be switched on because a roaming SIM uses other operators’ mobile networks to connect to the internet. If data roaming is switched off, the phone or router may still find a mobile network, but internet traffic is blocked. It then looks as if the SIM card is not working, when in fact only […]
Yes, a roaming SIM can give 5G if 5G is available and the local operator allows 5G roaming. To use 5G you also need a 5G router or another device that supports 5G. With a 4G router the connection only uses 4G, even if the SIM card and mobile network support 5G. If you travel […]
If you only get 4G, first check whether your router supports 5G at all. A 4G router cannot connect to 5G, even if the SIM card and the mobile network support it. This is especially noticeable in Germany, for example, where 4G in some areas can be both slower and more heavily loaded than 5G. […]
Yes. If you use a Europe roaming SIM, data roaming must be switched on in the router, phone or device the SIM card is in. Why is roaming needed? The roaming SIM connects to different mobile operators’ networks depending on the country. If roaming is switched off, the device can therefore have reception and still […]
Yes. A roaming SIM can connect to different partner operators depending on the country. We normally recommend leaving network selection on Auto, as the router then chooses an available network itself. But if the connection is slow or does not work, you can choose the operator manually in the router’s network settings. Search for available […]
If roaming is switched off, the SIM card cannot connect to the mobile network outside its home country. The router’s Wi-Fi may still be visible, but you have no internet connection. With our Europe or roaming SIMs, data roaming must always be switched on, in the router or in the device the SIM card is […]
Yes. We normally recommend leaving network selection on Auto. The router then searches for an available mobile network itself and automatically connects to an operator that works with your roaming SIM. This is especially practical when you travel between different countries and regions. But if the connection is slow, unstable or does not work at […]
No, it depends on which SIM card and which data plan you have chosen. Most of our roaming SIMs work throughout the EU, and some data plans also include countries outside the EU, for example the United Kingdom and Norway. Always check before you travel which countries are included in your data plan. You will […]
Before your trip, the most important thing is to check that your roaming SIM is active, the right data package is chosen and the country you are travelling to is included in the data plan. Also check that data roaming is switched on in the router or phone and that network selection is normally set […]
