HomeSMS Features › Manage SMS Route

Manage SMS Route

Block or unblock specific country prefixes to control where your SMS account can send messages.

What is SMS Route Management?

The Manage SMS Route feature allows you to control which mobile prefixes and countries your iSMS account is allowed to send SMS to. This is useful for businesses that only send to specific countries and want to prevent accidental sends to unintended destinations.

How to Access Route Management

Log in to your iSMS member account. Go to Profile → Manage SMS Route.

iSMS Manage SMS Route — navigate to profile

Viewing Available Routes

A list of all available country and network prefixes will appear. Each prefix can be individually blocked or unblocked.

Blocking or Unblocking Prefixes

Select the prefixes you want to modify — tick individual rows or use Select All to select all. Use the alphabet sidebar to quickly find countries by name (e.g. click M for Malaysia). Choose Block or Unblock from the status option, then click Update.

💡 Tip: If you only send SMS within Malaysia, consider blocking all international prefixes to prevent any accidental international sends that would consume more credits.
