Callny G202 PLUS Setup Guide: SMS Commands and Configuration
Complete Callny G202 PLUS setup guide: nano SIM, wiring, alphanumeric passwords, auto-assign slots, user roles (G203), relay timing, and key command differences from RTU5024.
The Callny G202 PLUS (also sold as Daniu GSM, LPSECURITY, and CY305) is the third most popular GSM gate opener module. It uses a nano SIM instead of the standard SIM used by RTU5024 and Waferstar, supports alphanumeric passwords up to 12 characters, and has three-tier user roles in the G203 variant. But finding clear English-language setup instructions is nearly impossible.
What Makes the Callny G202 Different?
The Callny G202 PLUS is a GSM relay controller that opens gates via phone calls and SMS commands. According to the manufacturer documentation, it shares the same basic principle as the RTU5024 (authorized callers trigger a relay) but differs in several ways:
- Nano SIM instead of standard SIM (same format as modern phones)
- Alphanumeric passwords up to 12 characters (vs 4-digit RTU5024)
- Auto-assign user slots with the DEF command (vs manual slot assignment)
- Three user roles in the G203 variant: Super Admin (TOP), Admin (ADV), Normal (NOR)
- Delete by phone number as well as by slot (RTU5024 only deletes by slot)
Step 1: Prepare the Nano SIM
Insert a nano SIM into a phone, disable the PIN lock, verify voice and SMS work, and note the phone number. The Callny uses a nano SIM (the smallest format), which is the same size used by modern smartphones. No adapter needed.
Step 2: Insert SIM and Connect Power
Power off, insert the nano SIM, connect 9-36V DC power to V+ and GND. Wait for the SIGNAL LED to stabilize (slow blink every 3 seconds = network registered).
Step 3: Wire the Relay
Connect COM and NO to your gate motor's "open" button terminals. Same principle as RTU5024 wiring.
Step 4: Add Your Phone Number (First User Becomes Super Admin)
The first authorized user automatically becomes the Super Admin (TOP). Send:
Command: {password}#TEL{phone}#DEF#
1234#TEL+31612345678#DEF# Response: Super User added, User ID:001
The DEF command auto-assigns the next available slot.
Step 5: Change the Admin Password
Default admin password is 1234. Change it to something stronger (up to 12 characters, letters and numbers):
Command: {password}#PWD#{new}#
1234#PWD#newpassword# Step 6: Add More Users
Additional users are added as Admin (ADV) by default:
newpassword#TEL+31698765432#DEF# On the G203 variant, you can also add Normal users who can only call to open (no admin access):
newpassword#NORTEL+31655555555#DEF# Step 7: Set Relay Timing
The Callny uses a different format than RTU5024. To set relay time to 5 seconds:
Command: {password}#GOT{seconds}#
newpassword#GOT005# Values range from 000 (toggle) to 999 seconds. Unlike the RTU5024's half-second increments, Callny values are in whole seconds.
Step 8: Test
Call the module's SIM number from an authorized phone. The gate should open.

Frequently Asked Questions
Is the Callny G202 the same as the Daniu GSM or CY305?
Yes. The same hardware is sold under multiple brand names: Callny, Daniu GSM, LPSECURITY, CY305, and CN G202. The SMS commands are identical regardless of branding.
What's the difference between G202 PLUS and G203?
The G203 adds a third user role (Normal/NOR) for users who can only call to open but cannot manage other users. The G202 PLUS has two roles: Super Admin and Admin.
Can I use a standard SIM with an adapter?
No. The Callny's nano SIM slot is too small for an adapter. Use a nano SIM directly.
