Drive
Why does it stop working if the car hasn’t been driven for a long time ?
Needs Improvement
The device itself works on and off ? I have read some of the same issues i myself am experiencing.
Bottom line is ? The app works as it should when it wants ? Get the bugs fixed and would be a pleasant experience !

Annoying af
I thought it was a great idea to get this for both my cars. The notifications come in repeated and it’s very annoying. Some days I just want to remove it from the car and toss it in the trash. When I needed it the most I spoke to 3 different reps and all told me something different. After 2 hours on the phone I never got towed. I had to resolve the issue on my own. If I knew then that I would have these issues I would’ve never bought into this. When I called to complain the rep kept saying I hear you. But did she really? I don’t think so. I asked several times what is T-Mobile going to do to compensate me? She never replied.

This app is terrible. I’ve tried for days to get the app to work and/or sync to the port.
Frustrating Experience with Sync up Drive Endless Sync and Location Issues
I’ve been using Syncup Drive, and while the idea behind it sounds great, the execution is full of frustrating bugs that make it nearly unusable long-term.
1. Constant Reconfiguration Needed
Even though the Syncup Drive device is connected to the car, the app constantly thinks it’s a brand-new vehicle. Every time you start the car, it acts as if it’s never seen it before. You end up having to add new cars and new profiles repeatedly.
2. Frequent “Merge” Prompts
After adding duplicate cars (profiles). It’s confusing, time-consuming, and feels like the app doesn’t recognize its own data.
3. Incorrect GPS Location
Another recurring issue is the car showing up in completely wrong locations. More than once, it’s shown my car as being in North Dakota when I’m actually in Florida. This isn’t a one-time glitch; it happens frequently and makes tracking unreliable.
4. IMEI Confusion
To make things worse, you practically need to memorize the IMEI numbers of your devices just to manage your cars properly. Each time the app resets or loses sync, you have to reinstall the profile and reassign the correct IMEI to the right car manually.
In summary: Drive One feels like it’s still in beta testing. The concept is promising, but the current experience is buggy and far from seamless. Until they fix the syncing logic, location errors, and repetitive reconfiguration process, it’s more hassle than help.

Needs Improvement
The app needs improvement, such as the notifications are truly annoying. The app doesn’t need to notify me if I start and end my trip. When you turn off the app notifications, you would expect it to stay off, but it doesn’t.
My other issue concerns the hotspot and the app itself. The communication between the two, tends to disconnect, when the device is plugged in.

Awesome app
Makes feel safe when your away from your car
Paying for the service but not working
I’ve been paying for the service for over a year and a half and it’s not working until finally like three months ago. I’m thankful the service is working because this is a really die to hard app when doing business or using your laptop or tablet or any device you want to connect to the Internet like at home in the car instead of having a mobile hotspot I’d rather have a strong connection with a device that is incorporated into the car that goes with the car applications and using the car software and updating the card itself using the hotspot from the SyncUP DRIVE not mobile hot hots

Won’t work
No WiFi connection.
Great app except the speed limit
It’s a great app that works well. However, the speed limit is set by users and it doesn’t reflect the actual posted speed limit on the road. The developer should connect the speed limit to the actual road and warn drivers if they exceed the limit.
FULL of Bugs!
This is one of the worst apps I have used lately and am surprised the quality is so low from such a major company.
On the latest iOS 26.0.1 trying to setup my new SyncUP Drive, and when it asks me to name my car, the Next button does nothing. I couldn’t get past this screen until I tried many attempts to tap the button. I don’t have any problems with buttons on any other apps, just this one. Does T-Mobile test this app??
I have an active diagnostic trouble code (DTC) for the EGR flow on my 2001 GMC Yukon, and this was a good opportunity to see how this app reports the DTC. While it reports there is an active code, it displays NOTHING whatsoever about what the code actually is. Disappointing.
When I unplugged and replugged the device to the ODB2 port, it reset all of my SyncUp Drive app notification settings for no reason.
The battery monitor only tells you if the battery is good or not, but does not show a graph of battery level history which would be a lot more useful to see any charge and drain trends.
There is no setting to extend the duration of WiFi hotspot beyond engine off. That is a big missing feature, as sometimes I like to continue to have my devices connected to WiFi when stopping briefly to get gas etc.
Sometimes the app crashes and takes me back to the iPhone home screen, or hangs when first starting up and then I have to force close it and then start it again.
When I used to have Verizon Hum+ (now being discontinued) their app was 100x more reliable and with more useful features.
This app is junk and T-Mobile needs to completely redo it and add a lot of missing functionality that the device hardware is capable of.
Why can’t it even show the DTC??

Vehicle tracker works pretty good
I installed sync up drive tracker on my vehicle and it works pretty good most of the time . Another feature I like is that it saves a complete history of everywhere your vehicle goes and anything it detects along the way , like if your speeding or any diagnostic codes your vehicle computer has or even you fastening or unfastening your seatbelts. Bad points . Sometimes it gives false readings ie: it will notify you your vehicle is moving when it’s parked . Scared the heck outa me once , was at Walmart and thought someone was stealing my vehicle, ran out to the parking lot to find it parked where I left it. 🤪as well as disturbance alerts like if it’s thundering or giving me the wrong location like where I was at and it still showing I’m parked where I was previously at not where the vehicle is actually at. So what I did was install a camera in the vehicle so I can look at my camera when I get an alert . 1 thing leads to another . But overall worth what it cost even if it gives you false alerts sometimes .

SyncUP drive is one of the best tracking devices for your vehicle. Not only does it give you step by step live tracking it also tracks any issues with the vehicle

Save Your Money. Get Something Else
The app keeps sending notifications of “new car added” although the car has already been registered. And forces me to re add a new vehicle everytime I start up the car and disables the old profile. Spoke to T-Mobile support and they said “yeah the app is really bad and we get calls everyday about those same issue. You will just have to wait for an app update.”
Totally not worth it. I would go with other options for sure.

syncup drive
this app is freaking amazing. I love it. I love T-Mobile of course T-Mobile loves me too. I know it because I write reviews all the time and I enjoy being a member and part of the team of T-Mobile. I am so glad that I end up getting this for my vehicle tells me everything I need to know about the vehicle as well as given my family access to Wi-Fi and no one where my car is at all times thank you T-Mobile for being such a great provider. Screw you Xfinity at least T-Mobile gives me rewards. Offers you cannot keep up with T-Mobile because T-Mobile is the best never switched over to Xfinity ever again.
