I can receive texts , make and receive phone calls but cannot send any text to any number - "Message not sent"
Welcome to the community and thanks for posting. I'm very sorry to hear you're not able to send text messages.
What is the make and model of handset you're using?
When did you notice this stopped working?
Is your SMS Centre number set to +447958879890?
The phone I am using is:
Sudroid 2.4inch MINI Smart Phone Android 4.3 MTK6572 2 SIM WIFI 3G
but through Amazon.co.uk
Yes I was already checking the SMS Centre number set to +447958879890 following your telephone support technicians
It stopped working around October 11th, 2017
Are you texting a UK or international number?
If you put the SIM card in another handset does the same happen?
I have tried UK and international (Irish) numbers with the same results. I don't have any other handset to try. Is it possible to get a replacement SIM card to try?
I'll send you a private message to discuss further. To view this click on the purple envelope on the top right.
Hope to hear from you soon.
