In such a scenario, if you happen to lose your mobile, there’s a high risk of fraudulent activities being involved. For example, if you lose your phone that has been synced with your bank account, anyone can access your details. Moreover, if you decide to change your SIM and casually dispose of your old SIM, there’s a risk of someone else accessing the SIM.
