I recently placed an order for a cellular booster and I've realized that the model I selected isn't compatible with my phone. After reviewing the specifications, I believe the unit I actually need operates at a different frequency. Is it possible to exchange my current order for the correct model? I'd appreciate any guidance you can offer on how to proceed with this change. If there are any additional steps I need to take or any fees associated with the exchange, please let me know. Thank you for your assistance!
