What is SMS routing by country?

A rule that picks which SMS supplier sends a message based on the recipient's country code, so each country uses the supplier that suits it best.

Will customers notice a different supplier?

Usually not. What they can notice is the sender: some countries restrict alphanumeric senders or require registration, so check each country's sender rules with the supplier.

What happens if a supplier fails?

With a fallback rule, a message that fails on the first supplier is retried on another one you choose.

Do suppliers bill through Arino One?

No. Each supplier bills you directly on your own account, with no markup.

SMS Routing by Country: Cut Cost Without Losing Delivery

SMS prices and delivery quality vary by country and by supplier. Instead of sending everything through one supplier, you can send each country through the one that suits it — and keep a fallback so a bad day on one route doesn't stop your messages.

In Short
Pick a supplier per country code, add a default for everything else, and add a fallback for every rule. Compare on delivery as well as price.

A Worked Example

Country	Route through	Fallback	Why
Germany (+49)	seven	Infobip	A German supplier for German numbers
United Kingdom (+44)	GatewayAPI	Infobip	A European supplier with UK coverage
United States (+1)	Twilio	—	Your registered US numbers already live there
Everything else	Infobip	Twilio	Broad global coverage as the default

This is a sample setup, not a price claim. Whether seven or GatewayAPI is cheaper for your traffic depends on the rates on your own accounts; check each supplier's current price list [Source Needed].

Things That Change Per Country

United States: application messages from local 10-digit numbers need A2P 10DLC registration with US carriers (Twilio docs). That registration is tied to the provider where you made it, which is why the example keeps US on Twilio with no fallback.
Sender names: some countries require alphanumeric sender IDs to be registered before use; requirements differ per country and per supplier [Source Needed].
Delivery reports: judge a supplier on the delivery updates it returns, not on price alone. A cheap route with poor delivery costs more in the end.

Set It Up in Arino One

Add each supplier under Settings → SMS Suppliers → Add Supplier. See Connect an SMS Supplier.
Create a rule per country code. See Routing Rules by Country.
Add a fallback to each rule. See Fallback Rules.
Send a test to a number in each country with Test Messaging.

When Not to Bother

If nearly all your SMS go to one or two countries at low volume, one supplier with a fallback is enough. Routing pays off when volume is spread across countries.
