Choose the plan by the application’s actions
Crypton lists Reply at €89 monthly and Full at €129. Full adds proactive outbound work and new group chats; Reply is intended for receiving and responding. Monthly and three-month terms list a €29 setup charge, waived on six- and twelve-month prepayment. Availability depends on country and device stock.
Keep incoming and outgoing capability separate
The FAQ says the line can receive SMS while outgoing messages use iMessage. Model those as separate capabilities rather than a general multichannel boolean. If the recipient cannot receive iMessage, ask the provider what result the application receives and what recovery path is supported.
Confirm the country, sender identity and exact plan before coding assumptions into a workflow. A price in euros and a hosted line description do not establish availability in every market.
What we would verify first
Use a consenting test group to check an inbound reply, a proactive send on the appropriate tier and a recipient outside the supported channel. Inspect the resulting status and the operator’s view.
This is a relevant candidate for a business whose geography and channel requirements match the product. An application that requires automatic outbound SMS fallback needs a different confirmed capability, rather than treating SMS reception as evidence that the requirement is met.
