What is Phone Unlocking?

A cell phone unlock code removes the carrier restriction from your GSM (SIM card capable technology) phone. This will allow you to use a single mobile phone on any worldwide GSM network. Having an unlocked phone will allow you to use a prepaid SIM card in your destination of travel. With an unlocked cell phone, you will be able to obtain a local cell phone number and pay local rates instead of the ridiculous roaming fees that carriers charge. Your savings on roaming fees will be incredible regardless if you are someone who travels internationally once a year or every week. Cellfservices has written a case study to exhibit a clear understanding in the potential savings while traveling internationally. Read about how to save money on your wireless roaming bills here.

How to Unlock a Phone

Cell phone manufacturers integrate a method to input an unlock code into your phone to remove the SIM lock. All we need are 3 pieces of information to start unlocking your phone. First, we will need the IMEI (Serial number) from your phone, which can be found on all GSM (SIM card capable technology) phones by pressing *#06#. The IMEI is typically 15 digits long, while some have 17 digits. Second, we will need the network carrier that your phone is locked to. Finally, we will need the model of your phone to generate an accurate unlock code. After, a representative from Cellfservices will e-mail you the unlock code with simple unlocking instructions. Written instructions can be found by selecting your manufacturer from our unlock code page. Also, we are continually working on making unlock code videos and providing them on our Youtube channel.

Which Phones can be Unlocked

Virtually all GSM phones can be unlocked. This includes unlocking Blackberry, HTC, LG, Motorola, Nokia, Palm, Samsung, Sidekick and Sony Ericsson cell phones and smart phones. Most phones with a SIM Card slot located behind the battery can be unlocked.

How Long will it Take to Receive my Unlock Code

All of our unlock codes are processed quickly and accurately. The processing time for your unlock code will depend on the model of your phone and the network carrier it's locked to. Most of our North American codes return within 24 hours, while others are much faster and others slower. For example, a BlackBerry unlock code normally takes 5-15 business minutes while some Nokia phones may take several days to retrieve. We pride ourselves in our BlackBerry unlocking service. As a result, we've had a 100% customer satisfaction rate with our happy clients who purchased a BlackBerry unlock code.

Unbelievably, it took two hours just to unlock my T-Mobile iPhone 17 Pro Max.

Al inicio dudé bastante porque el proceso tardó más de lo normal. Pasaron los 5 días estimados y ya estaba pensando en cancelar el pedido. Sin embargo, decidí esperar un poco más… y valió la pena. Al día 9 recibí confirmacion, lo probé y funcionó al 100% sin ningún problema. Servicio real, efectivo y confiable. Aunque tarda un poco más de lo esperado, cumplen. Totalmente recomendado. ⭐⭐⭐⭐⭐

True to their word! If they can't unlock it you don't get charged. Just let them do their "magic" and before you know it they will email you and inform you on your status. I ran my iphone (SE 2016) first thru (clean) and came back telling me I had to send it thru (pro), didn't charge me. Yes (pro) is a little more, but worth it to me. A few days later got an email telling me my iphone was unlocked. That simple! Thanks Unlockbase!!
