Before you start, make sure you have a compatible Micro Sim-Card (more details here), then download and install the Tinitell mobile app.
Setting-up you Tinitell for the first time
Here's a demo on how to set up your brand new Tinitell (it's better to have your Tinitell charged at least 50% when you start the setup). Keep the Tinitell tiny screw driver and the product manual close at hand.
Time to add Tinitell to your account
During the process Tinitell should be close to the smartphone where you have installed the app. Tap on "Get Started" in the Tinitell App, and it will take you through the steps of creating an account and add your first device.
If there is more than one Tinitell nearby, a list of the different Tinitells will appear. Select the one whose 4 digits correspond to the last four digits of the IMEI number of your device (you can find the IMEI number in the box, and also on the bottom cover of your Tinitell). It might take some time while the scan process takes place.
Open the mobile app and make sure Bluetooth is on. During this process Tinitell should be close to the smartphone where you have installed the app.
