An SMS-enabled virtual number can receive incoming SMS where supported. However, acceptance of virtual or VoIP numbers for account verification is controlled by the third-party service requesting the verification.
Some platforms may restrict or reject virtual numbers.
didlogic therefore cannot guarantee that an SMS-enabled DID will be accepted by a particular social network, messaging service, financial service or other third-party platform.
If you require numbers for a specific verification use case, particularly in volume, provide the target country, platform and required quantity before ordering so availability can be checked.
