A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Jelly is a mini-sized phone with full features of Android 7.0 Nougat and also the first of its kind supporting the ultra-fast 4G network. It is the ultimate answer to any situation where using a heavy, expensive primary phone is inconvenient.



Android Nougat, right out of the box.

Super portable

Jelly is designed to be small, but for a reason! whenever it is unnecessary to take a bulky and expensive phone with you, just put Jelly in the coin pocket.

3 colors available

Case Vs. Armband (band+case)

Since heard a lot of feedback about the concern on capacity, we decided to add an upgraded version, Jelly Pro with 2GB RAM & 16GB ROM.



Jelly On Press:

Small Yet Powerful

Jelly may look cute but it packs a punch! It uses a quad-core of 1.1 GHz processor up to 2GB RAM & 16GB ROM.



Dual SIM-Cards





We are travelers and we are business people just like you. Many people prefer to maintain more than one phone number and switching SIM cards to do so or when traveling is a hassle. Jelly makes it easy with dual Nano SIM card slots.



Battery Life

For many people, Jelly is a lightweight backup for their main phone and so it should be powered-up and ready to go when you are. Jelly has a replaceable battery design and with a full charge it has a upto 3 days working time (average usage) or upto 7 days on standby.



Workout with Armband



As smartphones have gotten bigger and more powerful, they have become cumbersome for activities such as running or working out. With Jelly, your workout is much easier. In fact, it’s such a popular use for Jelly that we designed a comfortable armband mount for sports and exercise.

Easy Selfie With Both Cameras

8MP back camera & 2MP front camera



Selfies made easy! No more struggling to hold and handle a heavyweight smartphone while trying to capture the perfect ‘You’.

Run Any APP



Choosing the mini-sized Jelly doesn’t mean compromising on your favorite Apps either. Using the latest Android operating system, Jelly can run virtually any App from the Google Play store.

Whether you want to play games or chat with friends, go ahead and fill Jelly with all your essential Apps and enjoy the convenience and reliability that you would expect from any phone.

Enjoy the Fast 4G Speed



Jelly supports most of the 4G network carriers except those with CDMA.

Our Proven Record of Making Mini-Smartphone

You may know us from our previous mini-smartphone. It was a great success and the result of years of experience and hard work perfecting cellphone manufacturing. It had a lot of happy users and they gave us valuable feedback about its present day limitations, such as only using GSM & 3G networks, limited storage and a few features they wish they had.

So we listened and went back to the drawing board to create a more advanced mini- sized smartphone -- the Jelly!
