Brand Custom Domain Setup
Point your brand to your own domain for your MVNO brand.
Connect your domain to Reach so customers use your brand URL. Choose nameservers (recommended) or a CNAME (fallback).
Overview
Reach can serve your storefront and My Account on your domain. You keep your existing email provider.
You have two setup options:
Update nameservers (recommended). Reach manages the DNS zone.
Configure a CNAME (fallback). You keep DNS with your registrar.
Default brand domain
If you do not want to use your own domain, Reach will provide a default brand domain:
www.brandname.thatsmymobile.com
This is the standard setup until your brand provides its own domain.
Before you begin
Have these ready:
Access to your domain registrar account
Your current email host details (Google Workspace, Microsoft 365, etc.)
The nameserver or CNAME values provided by Reach
Plan for 10–30 minutes of work. DNS propagation can take up to 24 hours.
Choose a setup method
Use nameservers unless you cannot transfer DNS control.
Root domain cutover is acceptable
Update nameservers
You must keep existing DNS records managed outside Reach
Configure CNAME
You are only connecting a subdomain
Configure CNAME
Option A — Update nameservers (recommended)
Use this when you can delegate DNS to Reach. This is the lowest-risk setup long term.
Option B — Configure a CNAME (fallback)
Use this method only if you need to keep existing DNS records in place and cannot transfer Nameservers.
Save and confirm
Save your changes and confirm to [email protected] that the CNAME has been added.
Validate the cutover
Once propagation is complete, run through this checklist to confirm your domain is set up correctly:
Your domain loads the branded storefront.
The browser address bar shows your domain.
SSL is active (lock icon).
Branded email still sends and receives.
Reach provisions SSL after DNS is in place. Allow up to 1 hour after propagation completes.
Email and DNS notes
Reach does not host email. Your existing email provider (Google Workspace, Microsoft 365, or similar) remains completely separate and should not be affected by this process.
To keep email running smoothly:
Keep your MX records pointing to your email provider — do not change these
Ensure your SPF, DKIM, and DMARC records are configured as recommended by your email host
Test sending and receiving emails before and after going live to confirm everything is intact
Already using Google Workspace or Microsoft 365? No additional changes are needed. Your MX records will remain intact.
DNS record types (reference)
For reference, here is a summary of the common DNS record types you may encounter during setup.
Record Type
Purpose
Example
NS
Delegates DNS management to Reach
ns-1234.awsdns-xx.org

Provided by Reach
CNAME
Creates an alias pointing one name to another
shop → brand.reachmobile.com
MX
Routes email to your email provider's servers
ASPMX.L.GOOGLE.COM
TXT (SPF)
Validates that emails are sent from authorised servers
v=spf1 include:_spf.google.com ~all
TXT (DKIM)
Digital signature verifying email authenticity
google._domainkey
TXT (DMARC)
Policy for handling emails that fail authentication
v=DMARC1; p=none; rua=mailto:[email protected]
Troubleshooting
Old site still shows after 24 hours
Clear browser cache.
Confirm the registrar saved the change.
Email delivery fails
Confirm MX records still point to your email provider.
Confirm SPF includes your email host.
SSL warning
Wait up to 1 hour after propagation completes.
Refresh and re-test.
Non-branded domain appears in the address bar
DNS is not fully propagated.
Re-check after a few hours.
Registrar navigation (quick reference)
Use your registrar’s DNS screen to edit nameservers or add a CNAME. Common paths:
GoDaddy: Domains → Manage DNS → Nameservers
Namecheap: Domain List → Manage → Nameservers
