Fears that mobile phones harm your health have been eased by a new report by scientists in Denmark.
They looked into concerns that using a mobile is linked to getting a brain tumour, quizzing over 1,000 people.
They talked to people who had brain tumours, and people who did not. They found that the people with tumours had not been using their phones more often. But the scientists warned that phones have not been around long enough for them to be certain of their safety.
In the late 1990s, the UK set up a group to look into the safety of mobiles. Its latest review also suggests the gadgets do not harm our health.
But experts have said that kids should limit the amount of time they spend chatting on their mobiles, just in case they turn out to be bad for you.
