Lokmat APPLLP 4 Z36 C17_D4 Official support thread

We are now official customer tech support for Lokmat products as well.

This is a great device and is not heavy or too big and looks great.
The second of the only two watches to have the higher speed ram - DDR4. Not sure how much difference this is going to make for daily use - but it’s a great time to find out.
Fantastic battery life from all initial reports.
Android 10, 4GB DDR4 ram and 128GB flash storage.
It is very similar to the LEM15 and uses the same Z36 main board.
We will also be looking at making a FW international firmware for this too.
However - the stock firmware on this and the LEM15 is a hybrid of both stock and FAW. I have to say it is greatly improved over the previous software package.
I have a promo code to save $20 USD if anyone is interested: LOKMATWATCH is valid until June 21st.
The official sales point is here: https://s.click.aliexpress.com/e/_9JmuRX

Details as follows and they are very honest figures :+1:

On the photo we see an error on the word TACHYMETER (TRCHYMETEA) and in real life on the LOKMAT APPLLP 4 smartwatch there is no this error it is well written TACHYMETER and it is very practical to calculate the speed we are going.


Is there anyone on the forum who has this model?

This is actually very true and you can immediately notice the difference in the stock firmware on these new products :+1:

Hi everybody. I’ve just received this smartwacht bu unfortunately it seems that it can’t connect to the network neither make phone calls. The issue, I think, is that the frequency of my SIM card (TIM ITALY) is not supported by the smartwatch…

I’m trying to change settings but nothing change. I’m afraid I’ll return the item.

Anyone could suggest solutions?? thanks

Factory reset and start again . After inserting sim card reboot watch . Hopefully that will work . Let me know . This should work in Italy just fine :+1:


There is a way to add a new APN in this hybrid firmware now.
But you will also need to check that the IMEI is ok after adding your APN.
In Settings, Network & Internet select Mobile Network and scroll down to the last setting “Access Point Names”
Then you can scroll down to “New APN” and add your provider APN.

The apn seems to be ok. I don’t know what else I can do

It may be that the imei number is blocked by your service provider.
You can contact them and ask them?

Maybe try a different telco Sim and see if it is ok…

You can see the imei number in watch settings / About Watch.

Hi everyone. The smartwatch can make phone calls only with a sim of VODAFONE network. Probably the only frequency supported…
