Hosted numbers provide you with an easy method to enable messaging on voice-enabled toll-free and local numbers (including landline numbers) that you already own. You can also use this method to move messaging services to Sinch if you have already enabled them with a different provider. Hosting numbers allows you to use Sinch messaging services and leave your voice services as they are.
You can also port numbers over to Sinch to use both messaging services and voice services. If this is the case, see this article about submitting a Letter of Authorization to port numbers.
Note: The text-enablement process in the customer dashboard is only supported in United States for toll-free numbers, and in United States, Canada, Puerto Rico, Guam or USVI for local numbers.
To host and enable text messaging on an existing voice enabled local or toll-free number, log in to the Sinch Customer Dashboard and follow the steps outlined below:
Choose the type of number you are text-enabling from the drop down. Select Toll free if you are text-enabling a toll-free number. Select Local if you are text-enabling a local number for 10DLC.
Enter the campaign ID for the numbers want to enable for SMS. Click NEXT.
This step is optional, and only applies to local numbers. If you click SKIP to skip this step, then you can only enable for SMS those local numbers which are not yet SMS enabled to prevent disruption to any of your existing numbers.
This is optional but it is recommended you specify a name, so your request is easily identifiable.
The SMS enablement process is only available for United States and Canada for toll-free numbers, and United States, Canada, Puerto Rico, Guam and USVI for local numbers. Select your region code from these options.
Specify your enterprise (work) email address.
Note: Personal email addresses (Gmail, Hotmail) are not supported.
Campaign ID (local numbers only)
Before you can use a local number to send any A2P messages you need a valid Campaign ID to show this is a valid approved A2P campaign.
Select your Campaign ID from the drop-down list. If you do not have a Campaign ID or want to create a new one, click the Create a new campaign ID link to create one. Refer to the Creating a new US 10DLC Campaign article for details of how to do this.
If you do not specify a Campaign ID you can still host the number on Sinch, but the number will not be SMS enabled and cannot be used to send SMS until you add a campaign ID.
Note: If your number has been previously text-enabled with a different provider, then skipping this step will interrupt your existing service. A campaign ID must be configured later to enable SMS.
(local numbers only)
A NetNumber ID (NNID) is used to identify the service provider for a particular dialed number and also supports MVNO-OTT override data for text messaging in North America.
This is optional. In most cases, you will not need to set this. Sinch will set this value for you to ensure proper message routing across all carriers. However, if do you have NNID(s) configured on your account you can select your desired NNID from the drop-down list.
SMS app ID
A Service Plan is assigned to you when you create an account on the Customer Dashboard - this is required to send messages using the SMS API. The SMS app ID is used to uniquely identify the Service plan.
Note: SMS app IDs are referred to as Service Plan IDs on the SMS tab of the Sinch Customer Dashboard.
Use your default SMS app ID or if you have more than one, select your SMS app ID from the drop-down list.
Select one of the three options:
Note: If you select the reseller option then the letter of authorization will state that the contract is between you (the reseller) and your end customer.
Current voice carrier
Specify your current carrier you are using for voice services for the number you want to host on Sinch.
Note: The LOA process will not affect your voice calling services and you may keep your numbers with your voice services provider without any porting required.
The process is now complete. Your number is now listed in the hosted numbers section and is ready to use for sending SMS messages.
Note: On average, the hosting process will take a few minutes when you are text-enabling a toll-free number that has not been previously text-enabled, or if you are text-enabling a local number for an existing 10DLC campaign. However, if you text-enabling a toll-free or local number that has been previously text-enabled, the hosting process can take 1-3 days. If you are text-enabling a local number for a new 10DLC campaign, the campaign must be approved by Sinch. In most cases, it will take the Sinch team 7-10 days to review and approve your campaign.
For information about managing your hosted numbers refer to the Managing your Hosted Numbers article.
To send or receive SMS messages with Sinch, you will need a virtual number from Sinch. A virtual number is a standard telephone number that is not locked down to a specific phoneline. It can route a voice call, text message or fax message to any phone or application workflow.
You can get numbers that are set up for SMS, Voice, Fax or a combination of these. You can buy a number from any country where Sinch has numbers in inventory. Countries with numbers available for rental are marked with Direct Access. All other countries will require you to submit a request to Sinch for manual handling.
Note: When you get a virtual number supporting documentation may be required and will need to be submitted before the transaction can be completed. If this is the case a message will be displayed at the bottom of your form (in an orange box). Learn more about supporting documentation.
To search for and rent virtual numbers:
|Enter the country you require a number for.
|If you are looking for a particular number, type in some of the digits you require in the Number.
|Select the type of number you require.
|Select the features for the number you require.
As an option for 10DLC numbers in the USA and Canada, you can also specify the campaign that you would like to configure the number on.
Note: This step is optional and you can specify the campaign later by selecting the Your virtual numbers option from the Numbers left hand menu.
If you click SHOW CONFIGURATION in the Setup section you can view details of the SMS and/or Voice configuration(s) for this number, which are automatically filled in:
However, if you have multiple configurations, then you will need to select the correct SMS and/or Voice, Fax configurations from the corresponding drop-down fields.
The details of the number you have purchased will be displayed in Your virtual numbers:
You can configure your number with an SMS, Voice or Campaign ID (only for 10DLC numbers) when you activate the number. Learn more about 10DLC Numbers.
When you get a virtual number, supporting documentation may be required and will need to be submitted before the transaction can be completed. If this is the case a message will be displayed at the bottom of your form (in an orange box). Learn more about supporting documentation.
