Shark 6 - SIM card issue

stegan | 2025-08-08 10:54 | 18 views

Hi, (Couldn't find a sub forum for the Shark - apologies to Dolphins and Seals) Great vehicle . Love the progressive performance and general build quality. Always makes me smile. The BYD App worked well for a week or so. Then stopped updating itself on 31/7. No more record of mileage, state of charge or notifications. Contacted the Customer support line and took out the SIM (under the drivers seat) and reinserted it. Factory reset the software. No improvements. Now the Navigation system has frozen in the wilds of Canberra! I'm in Melbourne...the car is not communicating on line. It just stopped. So. Checked on the forum on FaceBook - no offence but SO many more posters and information there... It appears that there are many customers with this same SIM card problem. Nothing can be done over the telephone. I have booked my car into a service centre (A few weeks time) Have been informed that there are batches of updates being released which may rectify the issue. Yet this falls short of good customer care? If someone has a problem, then just connect to that particular vehicle and issue an update? Send me a new SIM card in the post, just like my mobile provider? Pause. Rebalance my disappointment and growing frustration with BYD and put it into real world perspective. The car drives so well. I can use my ApplePlay for Navigation. Who cares if the car snubs me? It'll get over it one day....

That’s the way, chin up and if all else fails have a nice strong cup of tea, or if In Melbourne a cuppa coffee. But seriously, bloody annoying.

I have the exact same issue - stopped working 31st july and gps stuck in ACT when im in Perth after the factory reset. Yes very annoying - i guess ill have to book in for a fault investigation.

That fact that there are two cars (at least two) with identical symptoms means that there is a new disease out there. And despite the customer care agent advising me to hope it will be fixed if an 'over the air' update eventually reaches me, how will it communicate with the car? Of course it can't can it. If the SIM is not working, there will be no over the air update.

The only good news about this whole issue is that some of the finest coffees I’ve ever had were in Melbourne. I had an issue with not being able to download OTA updates a few weeks ago. Didn’t matter what I or the service department said or did the latest update just would not download ? I spent a considerable amount of time being told it would download, eventually, but being a very impatient chap I decided to investigate it myself and this is what I found. On my model there are two usb c ports at the front of the car. The one closest to the driver is a ‘data point’ as opposed to just a power/charger point ! What I found was that if you disconnect whatever you have plugged into that data point OTA downloads resume. I can only vouch for that working for myself and one other member, who replied in the positive when he followed my suggestion and removed the usb cable from that port. I hope this may be of help and if not then another coffee, very strong, may be in order. Be lucky

I've nothing plugged into the USB - so nothing to unplug...appreciate you reaching out to help. now on double Americanos... Costing me a pretty penny until the Shark gets a service look over on the 20th. Mobile & Wireless Accessories

Well at least the lane assist will keep you on the right track after all those strong coffees.

An update. I had booked the Shark into Essendon service centre today for the software to be updated - as advised by the telephone help line. In the hope that this may resolve the SIM card issue? This was many weeks ago... Polite and helpful service staff. Who confirm that there are many Shark owners with the busted TBox issue ( SIM card issue). FaceBook 'Shiver' site confirms many Sharks swimming mindlessly around Australia. Happily doing so without any communication with their handlers...fortunately their inherent strengths remain unaffected and are a delight to ride. And mine is one of them...of course the technicians are unable to update the vehicles software 'without' the TBox working. (some training required for telephone support staff?) The reluctant part has to be ordered from BYD China. And the car rebooked for when it arrives. Estimated a 4-6 week wait. That's on top of the wait I experienced until today... My suggestion to BYD who are clearly struggling with the success of their sales in Australia and haven't yet geared up in service and support. (Refer to the accessory debacle for so many customers) Why don't you just ship out a few TBoxes to service centres? Its a cheap part with a small footprint. Every single person has to get their car into a centre 'BEFORE' the part can be even requisitioned - and then another lengthy wait before the car can be rebooked for attention. My experience today will be replicated across Australia for many, many Shark owners with failed SIM card comms. And it's simply inefficient to double up on service centre time and energy and capacity? Could be doing routine services more promptly? It was a lovely sunny day for a drive in such a progressive vehicle...I must admit, so that's a good feeling. Yet. In my mind I had no confidence at all that BYD Essendon would be able to fix it today. Totally predictable outcome. Knew that they wouldn't prepare ahead. Very much 'in the moment' of their commercial sales success. Service needs improvement. Communications Equipment

Today I found out that my cars sim has stopped working, it appears to be a very common problem based on the tech who checked my can, he will a full test to confirm if the T-Box needs to be replaced. It sounds like BYD have to do alot more to fix this problem and not in their slow ways!!!!

(You have a Shark 6?) Definitely the current modus operandi for BYD when dealing with the failed T-Box on Shark 6. To make an appointment to bring it in before ordering a replacement part. Frustratingly, the diagnosis is quite straightforward for a customer - your SIM stops working! Your phone app no longer communicates with your vehicle. But BYD steadfastly refuse to have some replacement parts in stock (the T-Box is a most common issue on the Shark 6) So Bernard, you have to make that appointment and be sent home to await a part to be shipped from China and then make another appointment...this double process takes several months for most customers with this common issue. Over three months in mine. It's a saving grace that the truck continues to work well on its own without communicating with the App. I went back to Essenden on the 16th October and they fitted the replacement T-Box. All working fine for now. Remains a poor aspect of service support for a brand new vehicle...can't believe that there is no wit or local empowerment for service centres to hold a couple of boxes in stock...there are several service centres in Melbourne now - surely one of them could be a depot for the others and hold some T-Boxes?
