+Kinde encourages customers to configure their own SMS sender, so that verification, country registrations, sender IDs, and deliverability metrics are controlled and managed by you.
+
+When SMS messages are sent via Kinde, we will use our shared service provider in the region to deliver the message as best effort only. Due to Kinde being a service provider, there are some limitations with applying for dedicated short codes or sender IDs in countries that have strict SMS sending regulations.
+
+This topic describes SMS delivery via Kinde, deliverability factors, and some common reasons why delivery can fail.
+
+## Manage your own SMS sender
+
+By default, when you first start using Kinde, all SMS are sent from Kinde's shared service provider. It is recommended to configure your own SMS sender so that users receive authentication SMS that are branded by your business.
+
+You’ll want to configure this before your production environment goes live. All you need is to add SMS details in Kinde settings. See [Set up phone or SMS authentication](/authenticate/authentication-methods/phone-authentication/).
+
+## Deliverability factors when using Kinde's default SMS shared service provider
+
+Kinde provides no guarantees on SMS delivery and attempts delivery as best effort only.
+
+### Countries with known good delivery due to Kinde involvement
+
+The following countries have been tested and are known to have good delivery due to Kinde registering with the respective regulatory bodies.
+
+- Australia (LONG CODE, SENDER ID)
+- Canada (LONG CODE)
+- Great Britain (SENDER ID)
+- Ireland (SENDER ID)
+- United States (TOLL FREE)
+
+### Countries with known good delivery without Kinde involvement

+The following countries have known good delivery without Kinde registering with the respective regulatory bodies.
+
+- Generally the rest of the EU
+- South Africa
+
+### Countries with known bad delivery
+

+
+## Sender ID
+
+Kinde has setup a shared SenderID for all customers using the default SMS shared service provider. This cannot be changed. 
+
+Sender ID = ```KindeAuth```
+
+To brand the Sender ID to your business, you will need to configure your own SMS delivery provider. See [Set up phone or SMS authentication](/authenticate/authentication-methods/phone-authentication/).
+
+## SMS content
+
+The content of the SMS is not editable due to strict one-time passcode requirements and recommendations from industry best practice.
+
+An example of the SMS content is below.
+
+```
+123456 is your one-time code to sign in to {Business Name} 
+
+@business.kinde.com #123456
+```
