I am trying to verify Twilio integration of my Java app, at the moment I am using a trial version, and I am trying to verify that my App is able to send messages to the mentioned numbers, right now I am in India so the "TO" number is a Indian number, but the Trial number "FROM" number is a US number. I see that the messages are logged in Twilio Website, but I haven't received them on my Indian number. Smells bad? or its normal with Trail Account?
The problem is since I haven't been able to see messages in my phone, I am not sure should I go for the paid one - please help.
In addition, when i tried to verify my Indian mobile number I didn't the verification Code as SMS, so I tried the "Call Option" which worked for me.
Thanks and Regards, Boolean
Twilio Trial accounts can send messages to verified numbers only. I just set one up yesterday and was able to receive the messages while using my Trial. You can check which numbers are 'validated' for testing purpose by clicking the 'Numbers' tab, and then 'Verified Caller IDs'.
When logged into your Twilio account, click on 'Logs', then 'Messages' and you will get a list of all incoming and outgoing messages that Twilio has processed.
The messages may be being blocked because of Geographic restrictions. You can check on current geographic permissions and enable as necessary by clicking:
Top right - your email/profile pic. Then 'Account Settings'. This will bring up account settings page, as well as a tab of options at the top. Select 'Geographic Permissions' and make changes as necessary.
