Hi, I got a TKSTAR TK-915, using simbase SIM card.

The simcard works in other trackers like the sinotrakc ST915, however, in the TK-915, the yellow light keep solid instead of turning blinking once finding GPRS connection has mentionned in the manual.

Does anyone already have got this problem and a solution for it ? Is my tracker faulty ?

Your tracker is probably not faulty but communications settings are not correct. What country are you in? Did you send set up commands to the tracker? Who gave you a simbase card? I have over 300 of these TKstar units running and also use simbase. *Darrell R Wilson*

I'm in France, I bought 10 of simbase SIM cards.

I took one from a tracker that currently work for debugging, but can't get any response when sending begin123456 to the tracker (which seems logic because the yellow light is not blinking)

Do you have all the commands to set the tracker up? APN, IP/PORT and who is the monitoring company? *Darrell R Wilson*

Setting it with my own traccar server, self hosted.

The problem really is that I don't get any response when sending SMS

Read my question? I cannot help unless I know, do you have commands, did you set APN, IP/PORT? HOWare you sending commands? From simbase portal or some other way *Darrell R Wilson*

Yes I have the following commands :

• begin123456 (to reset hardware)
• adminip123456 traccar.mydomain.fr 5093 (to set ip port)
• apn123456 simbase (to set apn)
• gprs123456 to activate GPRS

I'm sending commands from simbase portal

I sent begin123456 but no answer from device and device still have no GPRS connection

Here is the way to find your problem or multiple problems? 1. Remove the simbase card 2. Insert a regular sim card from a cell phone (working cell phone) 3. The yellow light should blink and connect no matter what the settings are 4. If you get a blinking yellow light (may take up to 15 minutes) remove the cell sim card and put the simbase card back into the tracker 5. Send this command *reset123456* 6. Send this command next your APN *apn123456 simbase* 7. Send your IP/Port adminip123456 ***.***.**.* port number On Fri, Jan 16, 2026 at 6:51 AM Darrell Wilson < ***@***.***> wrote:

I would suggest this free site and set up to test the tracker! TK-Star TK915 | GPS-Trace <https://gps-trace.com/en/devices/tk-star-tk915#instructions> It is free tracking and the set up is more friendly than Traccar. On Fri, Jan 16, 2026 at 7:03 AM Darrell Wilson < ***@***.***> wrote:

Ok, so after some more investigations I managed to solve the problem :

1. I changed the SIM card using a friend one (I have only eSIM), and removed the SIM PIN code
2. Waiting for the tracker to get connection, it did quite quickly with this SIM
3. Sent :

• begin123456
• apn123456 simbase

4. There I lost the connection, and replaced the SIM card with the one from simbase
5. It got back the connection, now just setup the traccar server/ports

off topic but thought worth sharing. been using 2 yrs now.
1pmobile sim £48/yr.
renew every year.
works out £4/mth.
unlimited texts/calls. 500mb/mth data. designed for trackers..
runs off ee network 2G, 4G & 5G with EU roaming included.
https://www.1pmobile.com/siminfo?prodid=SBCT500.
costs £5 to replace sim if lost

Hi there !

As mentionned before I resolved the problem with the TK-915, however it was a 2G tracker, which gave me problems of data coverage, so I just returned it.

So now I bought a TK905C (4G version with 20000mAh battery). However I struggle at getting it working correctly... I managed to have it working with a SFR sim card (local provider in France). However whenever I put the simbase card in it, it won't find any connection.

What I did :

• apn123456 sl2sfr : set apn for sfr
• adminip123456 my.ip port : set to my server
• upload123456 5 : set upload delay to 5sec for debugging its easier
• gprs123456 : activate gprs

Then I could receive correct data on my server (port 5015 btw, hubauo protocol)

Now what I did after that :

• apn123456 simbase
• check123456 : replied with TK905ZF690CJTS60601#250509,,ID:959XXXX,IP:213.XXXX,5015,apn:simbase,apnusername:,apnpassword:,GPS:12,LTE:31,CENTER:,SOS:,,,
• Remove SFR sim and replace with simbase one

Now the tracker wont find any connection and wont send any data to my server.

The simbase's SIM inside is a SIM that works in another tracker for my bicycle, so it is activated, and supposed to be functionnal.

I know I'm a bit off topic, but maybe this happened once to @wilsonsecurityagency-investigator or might talk to someone in there... Maybe it could help another person later!
