How to fix?
First, make sure that we do not interfere with common reasons like:
- No signal. If the smartphone does not catch the network, there’s nothing to be done – you need to look for a place where there are no problems with the reception.
- Poor reception – one “circle” or the inscription “Search”. The advice here is the same as above – find a place where the network “catches” better.
- SIM card not working – for example, you have not used the SIM card for too long, and the operator blocked it or did it fail at all.
- Subscriber (SMS recipient) number is disabled. This happens if the addressee has recently changed the phone number, and you have not yet been notified about this. Alternatively, you have many phone numbers for this person, and you send SMS to an outdated one. Check the number!
- Active mode “In the airplane»(Airplane mode) – it disables the “telephone” part of the iPhone, including the SMS service. To disable it, open Command centre (drag your finger from the bottom of the screen to the center). If the icon with the airplane pictured on it is lit, touch it with your finger.
- Sometimes a simple reboot of the iPhone helps. To do this, simultaneously press and hold the power button and the Home button until the Apple logo appears on the iPhone display. After rebooting, try sending SMS again.
