3. Upgrading the Twilio account:

In order to remove the limitations on the account, you need to upgrade the account. To upgrade the account, choose the upgrade icon. You must enter your address and Credit/Debit card or PayPal payment details and charge your account by 20 USD.

4. Twilio guideline for sending and receiving SMS:

In my case I rent a UK phone number. I was able to send from that phone number to any international number. But I was not able to receive message to my Twilio UK phone number from non UK international numbers. I was able to receive only messages from only certain UK numbers. I asked the Twilio support and they gave me the following guideline and rules regarding sending and receiving SMS to Twilio phone numbers.

Sending messages to international destinations is supported by Twilio numbers. Please make sure you have done the below steps:

1. You have purchased SMS enabled Twilio number from the console https://www.twilio.com/console/phone-numbers/search.

2. You have turned on all the Geo permissions for the countries you wish to send to from here https://www.twilio.com/console/sms/settings/geo-permissions

3. You have read and applied the required rules by the country regulators in the guidelines pages of the country you want to send messages to it https://www.twilio.com/guidelines/us/sms

4. In case if sending messages to the US and Canada please make sure you only use a US or Canada numbers from Twilio as the US and Canadian networks accepts messages from only US or Canadian numbers, and if you try to send messages to any US/Canada number from an alphanumeric sender Id or a long code from other country that will not work.

The error explanation is here https://www.twilio.com/docs/api/errors/21612. The solution for this is to buy a US Twilio number from here https://www.twilio.com/console/phone-numbers/search and use this US number to send messages to the US or Canada.

5. Make sure you register an alphanumeric sender id if requested as mentioned in the country guidelines, and to register please fill this form here https://twiliodoer.secure.force.com/SenderId. This is required in Palestine. and without the registration messages won’t be delivered.

6. Please use this guide to get started and send your messages through Twilio API https://www.twilio.com/docs/sms.
