I picked up my Model 3 on Friday 3/23/18. I LOVE her! She is amazing. BUT, I am having trouble with the LTE connection. When I get into my neighborhood, I loose connection. I get nothing. When I leave my neighborhood, it's close to 10 minutes before I get a connection. Then I get to work and again, nothing. I have AT&T cell service on my phone, so I know the LTE is available in these areas. I don't know how I will get software updates if I don't have connection. I also really want to be able to adjust the climate before I leave from work but can't without a connection. I'm kind of bummed.
Anyone encounter this problem with their cars?

Oddly enough I have poor AT&T reception at home with my phone but the car seems to have a strong connection... go figure. I have lost LTE a few times (briefly), but it generally comes back quickly.

I would check with the service team for sure though.

Definitely contact Tesla service to see if there's anything they can check. You never know - there may be a loose antenna connection.

We believe that eventually Tesla will update the software to allow the car to connect to your wifi as well. The other models allow this, and I believe it's preferred to download updates over wifi.

Does anyone know what Carrier Tesla uses for LTE? Based on the responses above its probably not AT&T
It’s a good question. I have seen my phone and the car share the same brief dead zone on my commute home. I’m inclined to say it is AT&T and I suspect the car has a stronger antenna than my phone. Just guessing though...

I am looking forward to WiFi! But need connectivity when I am on the road, too. I would love to use the audio and navigation. I have an email into Tesla about this and a couple of other issues (panel gap and one panel sticks up). Just waiting to see what they say. Honestly, I am not upset, as I expected this as an early adopter. There were bound to be issues.

Sorry, a bit of a long post here. Hopefully, it will be worth the read.
Since I've picked up the car LTE connectivity has been spotty. Usually, after the car has been locked and has gone to sleep is when the problems happen. Sometimes I will not get a connection for the full drive sometimes after about 5 minutes it will connect. The issue has been consistently inconsistent. I called Tesla service and they have been very responsive. I have always been able to talk to someone immediately after calling. The tech I have been working with indicated that the LTE service is AT&T and that it looks like there is a bug that is delaying the sim card connecting. After attempting the usual series of reboots and powering off the car and looking at the car's logs he said he would need to escalate the issue to the engineers and he would get back to me as soon as possible. A couple of days later he said after meeting with engineers it looks like there are a couple of other cars with similar issues and my car is a test case on fixing the issue. We have scheduled me to bring the car to the service center today and they will try to get a fix worked out. Hopefully, I will get a Tesla as a loaner.

I'm having the same issue. It has only happened twice but both times it lasted 15 minutes or so. Both times were also along the 401 (Canadian highway) and in completely different areas.

I’ve had it happen to me twice in the last couple of days. Both times were when I got into the car and the screen was black until after I started driving. Both times were in different locations. Each time the LTE was out after the screen came back, but connected shortly after. I have not reported it to Tesla yet because the instances were short in duration.

I'm based near Toronto, Ontario, Canada - just took delivery of the Model 3 a few days ago. The LTE keeps dropping out. When it goes, it's off the air for anywhere from 5 to 15 minutes at a time. Major carriers cell signal are very strong in the area (full signal) Rogers/Bell/Telus. Called Tesla, they said a number of people in Canada are reporting this. I figured I'd see more talk of this online.

So, I have had my car since March, and I still can not get LTE to connect anywhere around my home or work, despite the fact that there is plenty of AT&T signal reaching my phone. I took the car in and they came back with nothing. They said the car is working as it should. I am actually glad to hear there are others in the same boat. I am a little frustrated that I can not connect. I really hope they figure out what is going on. Please let us know what they find. I have to take my car in for a few other oddities - crash sensor going off for no reason, mirror not unfolding at start of car, not recognizing my phone and asking for the card. Stuff like that. I would love it if I could tell them about a fix for the LTE. Thanks for being the test subject.

Update:
Picked up Grace today from the Westmont, IL service center. Have not had a chance to test it much but so far the LTE connection issue has not returned. The service tech said they replaced the LTE cell module. I am still having an issue with the automatic unlock but that seems to be an android Bluetooth issue separate from the LTE issue. BTW I was given a Model S 100D as a loner for the day. Awesome car but a bit scary driving a $110,000 car in Chicago construction traffic jams. All of the service people were great to deal with. The tech I have been working with over the phone called me after I picked up the car to see if the fix had been made successfully. We decided to have him call me in a few days to see if the issue is resolved so it can be rolled out to others with the same problem.

It's AT&T. But this was announced back in 2014, and it doesn't say how long the agreement was for, so it may have changed.
When we took delivery on May 15, I asked our delivery specialist what cellular carrier Tesla used and she said "AT&T".

We live in an area with a lot of very rural areas, islands and marine waters so cell coverage can be spotty but I've found the connectivity of the Car to be better than what I would expect with a cellular handset. It still drops out in known dead areas but seems to hang in there pretty good in weak signal areas. Sometimes I hear small dropouts in the music in weak signal areas but nothing major. So if it's worse than expected it might be a bad antenna or out of spec LTE radio module.

I've also driven a number of miles in valleys with zero cell signal from any carrier. The car carries on as normal, Bluetooth unlock works fine, GPS continues working (although without satellite images), and of course, there is no Internet music.

I picked up on June 6th from Toronto and I'm having this exact same issue. LTE will drop for 5-10 mins and is completely random when and where it drops.

I haven't contacted Tesla yet but it's on my list.

That might be an AT&T network issue. Their network can reach capacity at various times and locations. Hopefully, the extra capacity and speed enabled by their planned 5G build-out will alleviate this. The rate of growth of the demand for wireless data over the last several years is truly mind-boggling. LTE was the saviour until suddenly it wasn't enough! There is only so much bandwidth and the wireless gurus have to constantly work on making it carry more, faster. 5G brings new capacity in existing spectrum as well as new bandwidth (although the new bandwidth is a relatively short range technology).

Mine is like that even around Bay Area...it went to the service center now for changing LTE parts...will update my post with the service log screenshot...

I'm in Canada on the Rogers network so it can't be an AT&T problem. It feels like a problem with my Model 3's hardware or software. It's completely random and single strength in my area is strong. I can drive to the store and everything will be great. Driving home and part way thought the trip the LTE goes out and stays out for the next 10 minutes. 15 minutes here, 5 minutes there... this is not normal.

I will call Tesla and report the response. I look forward to reading others feedback in regards to the issue.

Substitute "Rodgers" in Canada for "AT&T". They are not immune to network capacity issues. The nature of LTE is that carriers decide how much they want to spend to cover a particular area. More cell sites can be added to increase network capacity (but not necessarily coverage). More cell sites in the same geographical area just increase capacity (but there is a limit as to how many cell sites can be added to increase capacity). 5G will alleviate this.

Also, having a strong carrier signal does not guarantee there is network capacity available. It's likely that Tesla's contract with Rodgers (and ATT) allow the network to prioritize their own customers (before Tesla's).

I've seen the same thing in Waterloo. I haven't kept track of the location, but I think it's more frequent near my home.
