Yes, FireText has the ability to instantly submit SMS messages to networks globally.
The slight complexity comes with the fact that each country has their own restrictions and filtering. These local network restrictions apply to all SMS with all SMS companies - We just like to be transparent about this.
FireText accounts, by default, are set up for UK-sending only as it allows UK-only senders more flexibility in uploading numbers. In order to get your account updated, to be able to send internationally, get in touch with the team via email@example.com
NOTE: When your account is updated for international sending, all numbers need to be uploaded in the international format e.g. UK numbers would have to be in the 447XXXXXXXXX.
