New smartphones often experience issues with SIM card functionality, leading users to face problems with network, calls, or mobile data. The actual cause is not a phone defect, but rather some essential settings. This problem can be immediately resolved by selecting the correct network type, enabling VoLTE and VoWiFi, updating APN, and allowing SIM permissions.
SIM Card Problem: Many users encounter issues like no network, inability to make calls, or non-functional mobile data after purchasing a new phone. This problem has been observed among customers of major telecom operators in India such as Jio, Airtel, and Vodafone-Idea. Most people assume it's a device malfunction, while the real reason lies in the phone's settings. In fact, some changes are necessary to activate a SIM card in a new phone. By rectifying these, users can benefit from network and internet services without any hassle.
Enable VoLTE and VoWiFi
Nowadays, Jio, Airtel, and Vodafone-Idea offer high-definition calling facilities to their customers. To take advantage of this service, it is necessary to enable VoLTE in the phone's settings. Furthermore, VoWiFi should also be enabled to maintain call quality in areas with weak network. This can be done by going to the SIM and network section and activating both VoLTE and Wi-Fi calling.
Select the Correct Network Type
The key to better connectivity lies in selecting the correct network type. Jio works only on 4G and 5G, while Airtel and Vodafone-Idea support 2G, 4G, and 5G. Users should choose the network type according to their operator. This option is easily found in the phone's settings under the mobile network section.
Update APN Settings
If mobile data is not working, it's possible that the APN (Access Point Name) is not set correctly. This setting tells the phone how to connect to the internet. To fix this, go to settings, open mobile network, then go to the APN section and select your operator's default APN.
Allow SIM Permissions
New smartphones require certain permissions related to the SIM card, such as SMS access and SIM toolkit access. If these are not enabled, it can lead to problems with services like OTP or mobile banking. To activate these, open the apps section in settings, tap on SIM toolkit, and allow the necessary permissions.
By making these simple setting changes, any user can immediately resolve SIM-related issues on a new phone.
