Send Outbound Messages
Two-way communication allows inbound and outbound traffic (messaging). For two-way communication, you need to have a two-way enabled number (VLN or Short Code). Your clients cannot reply to an alphanumeric sender. If you want your customers to be able to respond, there's always a dependency between Numbers, SMS, country, and usage.
Receiving Inbound Messages
In general, you can receive messages to your VLN sent from national as well, as international networks, but it's dependent on the mobile network operator roaming agreements. It is possible that in some cases only local networks are supported.
Also, in some countries, you can use numbers as sender names.
Once you have a number, you can implement any scenario you can imagine. The best approach to building complex integrated scenarios is to use the Infobip platform or integrate incoming messages in an existing business process using keywords and actions.
Each country has very specific country regulations when it comes to two-way coverage. Additionally, even different operators have different regulations and country limitations. For example, certain countries only allow Short Codes. Others, allow virtual long numbers (VLN). Some countries have multiple coverage options available. For SMS limitations, refer to Internation SMS Coverage and Connectivity. Contact your dedicated Account Manager or our Sales team for exact information on coverage, options, and fees.
