1
Use a dedicated line
Install Groupyid on a compatible Android phone and make it the default SMS app.
Local carrier messaging
One familiar number. The whole group included.
Groupyid turns a dedicated Android phone and mobile line into a carefully controlled SMS gateway, so smartphones and flip phones can participate in the same consent-based group.
How it works
Built around the phone line your group already understands.
The dedicated Android gateway receives ordinary carrier texts, applies local membership and safety rules, and queues approved messages for enrolled recipients.
2
Enroll with consent
Add members, verify exact numbers, and record permission before group traffic is sent.
3
Text the group number
Members send normal texts. Flip phones need no app, account, or data plan.
Local by design
Your Android phone remains the gateway.
The Stage 1 app has no Groupyid account, developer server, Internet permission, analytics, ads, tracking, contact upload, or remote backup. Carrier SMS/MMS still travels through the selected carrier and recipient devices.
No developer collectionApp data stays on the gateway.

Keep every kind of phone in the conversation.
Start in Dry Run, verify the gateway SIM and each member, then enable carrier delivery locally only after the group is ready.
