As part of ongoing carrier upgrades to support RCS, there are currently temporary restrictions on whitelisting iOS phone numbers for RCS test agents on AT&T and T-Mobile. These carriers have not yet enabled support for iOS-based whitelisting, but we anticipate this capability will be available soon.

In the meantime, Android devices across all major networks continue to be fully supported and can be whitelisted without issue. If you need access to an Android test device or eSIM for RCS testing in the meantime, please reach out to us at founders@trypinnacle.app.

Thank you for your patience as we work with carriers to expand platform support.

Given the recent rollout of RCS by carriers and extremely high demand for RCS functionality, carriers are currently facing long queues for approval with a preference for large well-known brands. Current approval times are increasing and range between one to several months so we recommend submitting your brand as soon as possible. Pinnacle will get you in this queue and navigate it for you so that your brand is approved as fast as possible.

While you wait for approval, Pinnacle is the only service that allows you to build test flows and send RCS messages to whitelisted numbers. Once you are approved, you can seamlessly and effortlessly switch to live agents by changing a parameter in your existing messaging flows.
