Samsung uses a Region Lock to prevent phones from being traded outside the intended region. You can recognise a Samsung smartphone with a Region Lock by the sticker on the box with "EUROPEAN SIM CARD ONLY".
This can cause problems if you want to use a non-European SIM card. Fortunately, it is very easy to solve the region lock. All you have to do is make calls for a total of five minutes with a European SIM card. After that, you can use any SIM card you want in any place you want. So it is important that you do this before you go abroad where you are going to use a foreign SIM card.
The Europe region includes all countries within the EU, plus the following countries: Lichtenstein, Iceland, Norway, Switzerland, Albania, Andorra, Bosnia and Herzegovina, Macedonia (F.Y.R.O.M.), Monaco, Montenegro, San Marino, Serbia, and Vatican City. So in these countries, you don't have to worry about the region lock.
Besides the internal storage of your device, you can also use Cloud Storage. Here you can upload your photos and videos, so they no longer have to be on your phone. They remain available on your phone via the Cloud, but do not take up any more space on your phone. In this way, your phone will stay fast and your storage will become much less full. Examples of Cloud storage are iCloud, Dropbox, Google Drive, and Microsoft OneDrive.
We understand that it is very annoying when the storage on your device is full. Fortunately, you can solve this with your device by inserting a microSD card. Your device has space for two SIM cards at the same time, as well as a microSD card. This way you can be reached on both SIM cards and you don't have to worry about the storage space of your phone. If you can't find where to place the microSD card, check your phone's manual. It often explains this.
If you get the notification 'camera error' this is often easy to fix. You can first try to remove the data from the camera application and do a software update. To do this follow these steps:
If these steps do not work, there is another way to fix the error. Resetting your device to factory settings almost always solves the problem. Please note: you may lose your applications and data. So first make a backup. A reset can be done as follows:
You can use two SIM cards with different phone numbers in a Dual SIM phone at the same time. Depending on the model, you can be reached on both SIM cards at the same time, or you can switch between them. This comes in handy if you have both a business and a private number, or a domestic and a foreign number. It depends on your device whether you can set up a separate ringtone for each phone number.
Switching between SIM cards and contacts is very easy, so you're always calling from the right number. The contacts are often sorted by SIM card. This way, you will always call your business contacts with your business number and private contacts with your private number. In a Dual SIM phone, you can also use only one SIM card.
