+              carrier specific restrictions regarding the frequency of outgoing/incoming messages. For Telnyx, the allowed SMS sending rate for US or 

+              Canadian long code numbers (10 digit numbers) is

+              message per 6 seconds per number</a> . If you need a higher throughput per number, you can rent toll-free numbers (with sending rates of 20 messages per second per number)

+              or short codes (with sending rates of 1000 messages per second per number). For Plivo, if you have rented a US or Canadian 10 digit number, you can send SMS messages at 

+              a rate of <a href="https://support.plivo.com/hc/en-us/articles/360041314852-What-s-the-outgoing-rate-limit-for-SMS-messages-" style="color:#1b60ba" target="_blank" 

+              rel="noreferrer noopener">1 message per 4 seconds per number</a>. If you need a higher throughput, you can rent toll-free numbers (with rates of 10 messages per second per 

+              number) or short codes (with rates of 100 messages per second per number). For Twilio, a US or Canadian 10 digit number can send

+              rel="noreferrer noopener">1 message per second</a>. If you need a higher throughput, you can send 3 messages per second per number with toll-free numbers, or 100 messages 

+              per second per number with short codes. For Flowroute, using a US or Canadian 10 digit number or toll-free number, you can send 

+              <a href="https://developer.flowroute.com/docs/flowroute-messaging-rate-limits/" style="color:#1b60ba" target="_blank" rel="noreferrer noopener">4 messages per second

+              per account</a> (accross all phone numbers). These sending rate limits don't necessarily apply when using non-US and non-Canadian phone numbers to send SMS messages to 

+              non-US and non-Canadian numbers. Also, in general, custom sending rates may be obtained by contacting Telnyx/Plivo/Twilio/Flowroute support. Starting from 2021, if you

+              SMS messages to phone numbers or from phone numbers belonging to certain carriers in the US, such as AT&T and T-Mobile, you will need to register your brand and your

+              Registered campaigns also benefit from a much higher message sending rate, which differs from one use case to another. If you leave the text box from below empty, the 

+              application will try to send all the messages with the default sending rate of 1 message per second. If you send messages from a US or Canadian long code number and you 

+              surpass the limit of 1 message per 6 seconds for Telnyx or 1 message per 4 seconds for Plivo, or 1 message per 1 second for Twilio, or 4 messages per second for Flowroute,

+              Telnyx/Plivo/Twilio/Flowroute respectively will queue your messages and will send them at the specified rates in the order they were received. However, if you send a large 

+              number of messages, when the queue becomes full, new messages can be rejected and lost, therefore, to prevent message loss, it's recommended to set the right sending rate 

+              in the text box from below.

+                The maximum length allowed for SMS messages using the standard GSM 03.38 encoding is 160 characters (fewer in some countries),

+                while for Unicode encoded messages is 70 characters. If you send an SMS message longer than 160 characters for standard GSM encoding or longer than 70 

+                characters for Unicode encoding, the message will be sent as a 'concatenated' message: it will be split into smaller pieces by Telnyx/Plivo/Twilio/Flowroute 

+                and it will be reassembled as one message at its destination. However, you will be charged for each piece as for a separate SMS. Thus, if the initial message 

+                is 385 GSM encoded characters in length, you will be charged for 3 SMS messages. The maximum number of characters per concatenated message is slightly smaller 

+                than the standard 160 for GSM encoded characters and 70 for Unicode, due to the inclusion of concatenation headers. Some symbols in the GSM 7-bit alphabet 

+                table (like "£" or "€") will count as two characters, therefore, not always 160 characters will fit into a single GSM encoded SMS message. The maximum length 

+                for MMS messages is different. MMS messages can be up to 1600 characters long.

-              Registered campaigns also benefit from a much higher message sending rate, which differs from one use case to another. If you leave the text box from below empty, the 

-              application will try to send all the messages with the default sending rate of 1 message per second. If you send messages from a US or Canadian long code number and you 

-              surpass the limit of 1 message per 6 seconds for Telnyx or 1 message per 4 seconds for Plivo, or 1 message per 1 second for Twilio, or 4 messages per second for Flowroute,

-              Telnyx/Plivo/Twilio/Flowroute respectively will queue your messages and will send them at the specified rates in the order they were received. However, if you send a large

-                The maximum length allowed for SMS messages using the standard GSM 03.38 encoding is 160 characters (fewer in some countries),

-                while for Unicode encoded messages is 70 characters. If you send an SMS message longer than 160 characters for standard GSM encoding or longer than 70 

-                characters for Unicode encoding, the message will be sent as a 'concatenated' message: it will be split into smaller pieces by Telnyx/Plivo/Twilio/Flowroute 

-                and it will be reassembled as one message at its destination. However, you will be charged for each piece as for a separate SMS. Thus, if the initial message 

-                is 385 GSM encoded characters in length, you will be charged for 3 SMS messages. The maximum number of characters per concatenated message is slightly smaller 

-                than the standard 160 for GSM encoded characters and 70 for Unicode, due to the inclusion of concatenation headers. Some symbols in the GSM 7-bit alphabet 

-                table (like "£" or "€") will count as two characters, therefore, not always 160 characters will fit into a single GSM encoded SMS message. The maximum length 

-                for MMS messages is different. MMS messages can be up to 1600 characters long.

+              Registered campaigns also benefit from a much higher message sending rate, which differs from one use case to another. If you leave the text box from below empty, the 

+              application will try to send all the messages with the default sending rate of 1 message per second. If you send messages from a US or Canadian long code number and you 

+              surpass the limit of 1 message per 6 seconds for Telnyx or 1 message per 4 seconds for Plivo, or 1 message per 1 second for Twilio, or 4 messages per second for Flowroute,

+              Telnyx/Plivo/Twilio/Flowroute respectively will queue your messages and will send them at the specified rates in the order they were received. However, if you send a large 

+              number of messages, when the queue becomes full, new messages can be rejected and lost, therefore, to prevent message loss, it's recommended to set the right sending rate

+                The maximum length allowed for SMS messages using the standard GSM 03.38 encoding is 160 characters (fewer in some countries),

+                while for Unicode encoded messages is 70 characters. If you send an SMS message longer than 160 characters for standard GSM encoding or longer than 70 

+                characters for Unicode encoding, the message will be sent as a 'concatenated' message: it will be split into smaller pieces by Telnyx/Plivo/Twilio/Flowroute 

+                and it will be reassembled as one message at its destination. However, you will be charged for each piece as for a separate SMS. Thus, if the initial message 

+                is 385 GSM encoded characters in length, you will be charged for 3 SMS messages. The maximum number of characters per concatenated message is slightly smaller 

+                than the standard 160 for GSM encoded characters and 70 for Unicode, due to the inclusion of concatenation headers. Some symbols in the GSM 7-bit alphabet 

+                table (like "£" or "€") will count as two characters, therefore, not always 160 characters will fit into a single GSM encoded SMS message. The maximum length 

+                for MMS messages is different. MMS messages can be up to 1600 characters long.
