Message Delivery


1. What is the maximum number of characters I can use for one SMS?

You can send messages up to 700 characters with SMS-Magic. If you are sending long messages, corresponding credits will be deducted from your account. For example, if you are sending a message of 350 characters, three credits will be deducted.

Long messages are broken into multiple parts and are concatenated after they are delivered at the recipient’s mobile phone.

The maximum number of characters for one SMS depends on the selected language. For instance:

  • 160 characters for only English messages = 1 SMS credit.
  • 70 characters for Unicode messages = 1 SMS credit.

Extended Characters as per GSM

Following are the extended characters as per GSM standard and would consume 2 character count(length) for each:

£, ^, {, }, [, ~, ], €, LF (Line Feed), CR (Carriage Return)

2. Which character is considered as Unicode?

Using the characters from the following list of ASCII characters are treated as GSM (i.e. Normal):

  • a-z
  • A-Z
  • 0-9
  • ~!@#$%^&*()-_=+][?<>,’.”:/\{}

Any other characters is treated as a Unicode (e.g. £). Therefore, if your message contains even a single unicode character then the message is treated as a unicode message and charged accordingly.

3. Can I use the same Sender ID across the globe?

The use of the same Sender ID might vary, based on compliance and regulations of the country where the messages are being sent. We provide global UK virtual numbers for you to use in sending your messages.

4. Can we reschedule a pre-scheduled SMS using SMS-Magic?

Yes, you can reschedule a pre-scheduled SMS. Just open the SMS details and change the time and date. Then click Schedule.

5. How do I get to know whether the number to which I am sending the message is a mobile number or a landline number?

Number lookup service can be used to validate numbers. Currently, we don’t have native integrations on Salesforce but the same can be enabled on request.

6. What are the different scenarios when my message would fail to/not be delivered? What are the delivery failure issues that could happen?

Following are the different scenario when the delivery of your messages would fail:

  • Number is Invalid and Not Specified in Correct Format – To avoid delivery failures we recommend keeping mobile numbers in the international format. For instance, within the UK the numbers you start with a 0 when calling or SMS (i.e. 01509 813888). However, for an international call or SMS to the UK you need to add the prefix (44) and remove the leading 0 (i.e. +44 1509 813888).
  • Carrier Spam Filters – Most carriers prefer to use regulations to control the flow of spam. In developing markets, however, technology is used to filter out unwanted texts and velocity. These filters, however, are not perfect and can lead to filtering out legitimate SMS traffic, as well. Some filters even send back a fake handset delivery confirmation. You think your message is delivered, but it is not. Furthermore, filter technology is in constant evolution, and associated algorithms change constantly. Keeping a track of which carriers filter and how, is a complex task.
  • Invalid Sender-ID – Frequently seen when trying to use non-authorized Sender ID in North America, where a long virtual number or short code is required.

7. What does “Rejected” Delivery status mean?

When the message delivery status is displayed as “Rejected”, it means that the messages are not delivered by the carriers due to Number Blockage or Velocity Block of Numbers. Most carriers prefer to use regulations to control the flow of spam. In developing markets, however, technology is used to filter out unwanted texts and velocity. These filters will send back a “Rejected” status if the message is undelivered due to Spam Filtering.

8. My Sender-ID is blocked by the carrier, how can I overcome this?

Carriers might block your sender ID temporarily or permanently.

  • Permanent block – You cannot use the Sender-ID as it is blocked permanently. You need to use a new number to send messages.
  • Temporary block – Your Sender-ID is restricted from sending messages for a few hours for not complying with the telecom regulations of a country. Once the block is lifted you can send messages again.

9. Can we bring in our own vendors?

If the vendor fulfils our on-boarding criteria then we can integrate it with our application. Presently, we can integrate with all major vendors.

10. Can I send SMS messages to DND activated numbers?

Depending on the country’s telecom compliance and regulations certain type of messages can be sent to DND activated numbers. For example, in India, you can send transactional messages to DND numbers but not promotional messages. To send transactional messages, you need to use a registered template and Sender ID.

11. What is your delivery rate for my country?

14. Is there a limit on how many SMS messages I can send with your application?

There is no limit on the number of texts you can send with SMS-Magic. However, you need to be careful while sending SMS messages in bulk on long codes. Carriers can block your Sender ID in case you cross a threshold limit, which is more than 10 messages a minute.

15. How many SMS messages can I send with a long code in the U.S.?

In the U.S., most carriers support 10 messages a minute. To send messages at a higher speed, we recommend you use multiple numbers instead of using a single number or leverage Short Code for the U.S.

16. How will you notify us when we get an incoming text?

We can notify you over email or SMS whenever you receive an incoming SMS in Salesforce. While setting up an alert on an incoming SMS, you can also specify to whom you want to send a notification. For example, if you send a text to one of your Lead records then you can define whether you would like to notify the owner of the Lead record or last sender of outgoing message.

17. When someone calls on my incoming number, what happens to those calls?

You have two choices:

  • Bring Your Own Number (USA) – Register the number with carriers, to use it as a Sender ID.
  • Missed Call on Special Number – The carrier provides a special number where a customer gives a missed call. This number only receives missed calls. You can then send required details via SMS to customers, in response to their missed call.

18. What is a shared long code?

A long code that you share with another company is a shared long code. Both of you will be receiving incoming messages on the same number. We will differentiate responses based on keywords and send you the responses that have come for you.
