this is a new unlock service so we don’t have a success rate as it is a brand new service we offer. Please only buy if you can bear with us if you need your device rushed, we do not advise you to purchase this until we have expected timeframe. so right now the timeframe would be ASAP. we can’t check upfront, you can buy it and then we’ll send it to our supplier and after that if it’s eligible for unlocking, it will get unlocked. If not, we can provide a reason why. if we can’t unlock it yes it will be refunded. after you buy you send us the imei number one, 15 digits, typed without spaces right here in the messaging system. Can you send me a picture of what it does when you put a different carrier SIM card? only for Clean & Unpaid Bills devices, NO OTHER ISSUES will be resolved here please send proof your IMEI is clean  ✅ We Support: Clean & Unpaid Bills
