French Guiana SMS numbers: distinguish +594 from Guyana +592

French Guiana is not Guyana

French Guiana uses +594; neighbouring Guyana uses +592. Arcep's French Guiana plan submitted to the ITU lists 694 for mobile numbers and 594 for fixed numbers, with a separate category for machine communications. This classification cannot identify a specific number in an SMS4U pool or guarantee that an app will accept it. Check that the app itself offers French Guiana as a destination before ordering.

Choose that same region and the app that will actually send the text. If the sender inserts +594 automatically, enter only the portion its field requests; do not double the country code. To compare Guyana +592, start a fresh app-country quote rather than editing an existing order.

Review the app, pool and receiving window together

The offers below separate WhatsApp, Facebook and other app products. Sharing a destination does not make those orders interchangeable. In the picker, compare the currently available Smart, Select, Flex and Global choices, then check the order window and final CNY debit. The USD figure on an English page is an indicative snapshot, not a held number. A short receiving order also cannot maintain a long-lived account or replace a recovery method you control.

Work out which step failed

If the app rejects the entry, verify the destination, number type and whether a national trunk 0 was included unnecessarily. If a pool is empty, return to current availability instead of repeatedly using an old quote. After acquiring a number, inspect the order timer and received-text status alongside the exact sender message. “Sent” in the app is not proof of SMS4U delivery. Voice calls, identity checks and local residency are outside this SMS order.
