I use Fongo mobile app on mobile device and have ported in my number from another carrier 10 months ago.
I use the basic fongo mobile app service that allows me to receive text messages and make free calls to local numbers and receive calls. I use whatsapp to text with my contacts. I have not purchased fongo text service and hence cannot send outbound texts using fongo. I do not have any other carrier service in my phone and fongo is my only number.
No major issues till two days back.
Two days back, Friend of mine told me he received a text from my number and forwarded me the message that was sent. Today, I happened to see his phone as well and I can clearly see the message in question showing under my number. He did a test message from his phone to see if it comes to my fongo app and I received the test message coming in as coming from his number.
So, without text feature in my fongo mobile app and no other carrier sms/text option to send outbound text, I am worried how is it possible for my friend to receive a text as if it comes from my phone number. I am worried if my fongo phone number has been hacked? Is it possible?
What are the options available to me?
What should I do next to make sure I am protected?
Should I continue to use fongo as my primary service provider for my phone number or should I port out to another non VOIP carrier?
Am I freaking out and/or are there other valid reason for this scenario to occur?
Please help. Thanks very much.
