Latest RSIM for Dual SIM iPhones: Unlock Guide & Compatibility (2025 Update)

Many clients are inquiring about the latest RSIM solutions for dual SIM iPhones, particularly for newer models like the iPhone 13 to 16 Pro Max. Below, we provide a detailed breakdown of compatibility, unlock modes, and best practices for optimal performance.

1. Compatibility: Which iPhones Support the Latest RSIM Unlock?

The newest RSIM unlock method is exclusively designed for:
✅ iPhone 13 series to iPhone 16 Pro Max
❌ Does NOT work on iPhone 7 to iPhone 12 Pro Max

For older models (iPhone 7–12PM), QPE mode (Qualcomm-based unlock) and Intel (TMSI) mode remain the most stable solutions.

2. Latest RSIM Versions: Glue vs. Fold (Single vs. Dual SIM Support)

The newest RSIM chips retain the same core technology but now support two different versions:

A. Glue Version – For Single SIM Use

Designed for single SIM card activation.

Requires placing the RSIM chip + SIM card in the secondary SIM tray.

Best for standard carrier unlocking without dual SIM functionality.

B. Fold Version – For Dual SIM Use

Supports two SIM cards simultaneously (no restrictions).

Ideal for dual SIM iPhones (e.g., international models).

No debugging, no signal loss, no IPCC loading required – plug-and-play activation.

⚠️ Important Note:

The new unlock mode only works for dual SIM slot iPhones.

Single SIM slot models (e.g., US/Canada variants) will NOT function with this method.

3. Best Solution for US eSIM iPhones (14/15/16 Series)

For US eSIM-only iPhones (14/15/16), if you have modified the device with a dual SIM tray (e.g., Wylie card slot), the RSIM with MEP mode is the most efficient unlocking solution.

Alternative Option: QPE Mode (For Single SIM Users)
If you prefer keeping eSIM + physical SIM (QPE mode), it remains a viable choice.

However, physically converting a single SIM iPhone to dual SIM requires additional hardware modifications, which may incur extra costs.

4. Final Recommendations: Which Unlock Mode Should You Choose?

iPhone Model    -  Best Unlock Solution
iPhone 7–12PM   ---> QPE Mode / Intel (TMSI) Mode
iPhone 13–16PM (Single SIM Slot)  ---> QPE Mode (eSIM + Physical SIM)
iPhone 13–16PM (Dual SIM Slot)  --->  New RSIM (MEP Mode) – Best Performance

Conclusion

The latest RSIM unlock method provides a seamless, no-hassle solution for dual SIM iPhones (13–16PM), while QPE mode remains the top choice for single SIM models. For US eSIM iPhones, hardware modification (dual SIM tray) + RSIM MEP mode delivers the best results.
