I'm sorry to hear that you're experiencing internet connection issues with your iPhone 11 on the Maxis network. It's essential to determine the cause of the problem to find a solution. Here are some steps you can take to troubleshoot the issue:
1. Check for Software Updates: Ensure that your iPhone is running the latest iOS version. Sometimes, software updates can address network-related issues.
2. Reset Network Settings: Go to "Settings" > "General" > "Reset" > "Reset Network Settings." This will reset your network settings, including Wi-Fi passwords and cellular settings. Note that you'll need to re-enter Wi-Fi passwords after doing this.
3. Toggle Airplane Mode: Turn on Airplane Mode for a few seconds, then turn it off. This can refresh your device's connection to the cellular network.
4. Check SIM Card: Ensure that the SIM card is properly inserted and not damaged. You can try removing and reinserting it.
5. Contact Maxis Support: If the issue persists, get in touch with Maxis customer support again. Request them to check the status of your account and ensure there are no network-related problems in your area.
Regarding the compatibility of iPhone 11 with 5G, it's essential to note that iPhone 11 models do not support 5G. They are equipped with 4G LTE capabilities. However, this should not affect your ability to connect to 4G or have stable internet access.
If the problem persists after trying the troubleshooting steps above, it's advisable to reach out to Apple support. They can assist you in diagnosing the issue further and providing potential solutions or repairs if necessary.
