1 Why No signals in Android?

Incorrect SIM Insertion
Sometimes users insert the SIM incorrectly, which causes the SIM signals to disappear, and you can’t use all the services provided by TM.
Physically Damaged SIM
Your SIM may be damaged. There may be scratches or a burnt chip; for that reason, your SIM is not detected, and the signals are gone.
Network Outage
A network outage by the SIM carrier can be the reason. Sometimes users face no services for calls, SMS, and internet because the system operator is down.
Poor Signal Location
You live in an area where weak signals come, and you are unaware of your location where signals work fast and smooth. You can’t make calls, SMS, or use the internet.
Enabled Airplane Mode
Another reason why your TM SIM has no signal is that you may have enabled airplane mode and forgot to disable it, so you can’t access the services.
Mobile Antenna Damaged
Most modern phones have an internal antenna in them. When a mobile is dropped, it can damage the antenna, which can cause weak signal or no signal issues.
Network Issues
If there are technical issues on the network provider’s side, then you may face signal disruption. It can even be due to a shark cutting the wires, which causes no network connection.
Phone Software Outdated
There can be bugs in outdated software that cause loss of signal and no services. Software glitches affect the connectivity along with other problems.

Note: Checking your TM SIM Balance through 143# code is the best way to check whether the signals are working or not.

2 Common errors in iPhone

You may have inserted the SIM in the wrong way in your iPhone, which causes the no signal problem.
Check your iPhone network settings to confirm if they are correct or not; wrong settings can block signals.
If you are living in an area where network provider towers are not set, you may face this issue.
If you have enabled airplane mode in your iPhone, you can’t avail services of phone calls, SMS, and internet.
Your SIM slot or SIM may be damaged, and even though you continuously try to access signals, it doesn’t work.
There might be mobile internal issues with the antenna or a network outage due to technical problems by network providers.
