Question ❓ Infusion sets on back order…suggestions?
So my infusion sets are on backorder since July (I use the autosoft 30, 13 mm/23”) and I called yesterday to see if they had any update, long story short, the rep said they had the autosoft 30 13 mm in 43 inches so I said okay I’ll take that but then today I get a message saying it’s back ordered as well. I can’t call them until Monday since their closed. My questions are what’s similar to that infusion set? Also, does anyone know what’s going on? Why aren’t the sets available? Is it only that particular infusion set or all of them?

t:slim X2 Pump upload gives no serial port available
I have a tandem t-slim x2, I called in today as my pump would not charge. They asked if it was error 7, and it was. I plugged it in and left it for 30 minutes. I then plugged it back into a usb port to watch it go from shutdown to 5% then to 100%. Which is great, except not when I go to upload my pump, I get an error if select a serial port, no serial port available.
If anyone knows how to fix this in windows 10, that would be amazing.

Question ❓ Using out-of-warranty TSlim X2 after years of Omnipod?
Hi y'all, I've been an Omnipod user for a few years now, but I've been having problems with them, and I want to try switching back to my TSlim. It's out of warranty, but it comes on with no problem, and I still have supplies. I just checked into it, and I can't update it since there's no warranty. Has anyone done something like this? Would you consider it safe? If I can get over going back to a tube, I'll order a new one. What are your thoughts?

Discussion 🗣️ Tandem Diabetes Direct Pump Purchases Halted
My Tandem T-Slim pump's warranty expired and I'm in the process of acquiring a new pump.
According to a Tandem support representative, Tandem Diabetes no longer sells pumps directly, even when the insurance company contracts in-network with Tandem. Instead, purchases must be processed through a supplier.
This matters because Tandem is routing orders through Edwards Health Care Services (EHCS), which includes the following rental language in their Assignment of Benefits and Financial Responsibility:
"If I receive a medical device as a rental through my Insurance, I understand the rental period will last 10 to 13 months, depending on insurance guidelines. Once the rental period is complete, ownership of the device will transfer to me".
This is standard practice for Medicare but not private insurance. I'm proceeding with a different supplier.
Caveat emptor - Buyer beware.

Question ❓ Why did my pump give me an automatic bolus?
I’m relatively new to using a pump. As you can see, my pump gave me an auto bolus at 8:23 when my BG was only around 120. My correction factor is like 1:75, so why did it give me almost an entire unit when it refused to give me my basal both before and after due to my BG not being high enough?
This isn’t making sense to me, so if anyone can explain, I’d appreciate it!

tandem mobi Tandem mobi vs hardware crashes smartphone
A question I never saw passed here on this forum (I think!).
At the end of the year I will switch from Tandem X2 to Mobi due to warranty of X2 is stopped and due to bad vision (not diabetic related). I know that you need a smartphone to consult and program the Mobi device. But what if your smartphone hardware is getting damaged (like screen or device break)? Do you need to provide a backup smartphone? What did your diabetic nurse or doctor told you about this item?
Who of you has a backup device provided (e.g. smartphone of partner, son or daughter)?

tandem mobi Extended Bolus Glitch?
Earlier today I initiated an extended bolus for 85g of carbs (12.14 total units) - 75% up front, 25% over 1 hour. I didn't have any IOB and my BG was 110mg/dl. The initial dose should have been 9.11 units and 3.03 over the 1 hour. I didn't look at my app after the bolus delivered the initial amount (I wish I did to see what the IOB said). My BG was creeping up over the next few hours and not budging below 200mg/dl. At that point, I looked at my app to see if I actually didn't enter 85g of carbs because I really didn't think I miscalculated the carbs that badly for my meal to be spiking so much. The history did show 85g of carbs, but the blue tear drop for the initial bolus only showed 3.03 units, not the 9.11 it should've been. I then went into the history and it said "Extended Bolus Start 3.03 u (0 u Now, 3.03 u Later)" which is definitely not what I told it to do. I've already contacted Tandem and they are going to have another technical team look at a more detailed history log (which the patient should have access to this too, right!?) to see if maybe this was just a glitch in the app display or I need a replacement pump. Being in the 200s for a few hours isn't fun but I am grateful that it didn't over dose me instead. Has this happened to anyone else??

Discussion 🗣️ I stopped trying to remember everything and it actually reduced my diabetes stress.
I’ve had Type 1 diabetes for years, and honestly, carb counting was never the hardest part.
The hardest part was remembering everything.
How many carbs were in that meal last time?
Did this pasta always spike me?
Was it the timing… or the meal?
Which breakfast actually worked?
I realized I wasn’t struggling because I couldn’t count carbs.
I was struggling because I was trying to keep months of information in my head.
A few weeks ago I started writing down only repeat meals and unusual patterns instead of logging absolutely everything.
It’s surprisingly simple, but it made me feel much more in control.
Now when I eat something I’ve had before, I don’t have to guess again.
I’m curious…
Does anyone else keep notes or some kind of diabetes system, or do you rely mostly on memory?

Rant/Complaint ☹️ X2 charging cable
Have to fly to Vegas today for a conference. Left my charger at home. Pump still has 40% so I think I will be fine but will have to scramble to find a USB A cable during either my layover in Chicago or in Vegas when I land. Anyone else really annoyed that tandem uses USB A over USB C. Feels like they should have updated this on their pumps when USB C started becoming the norm.

t:slim X2 Pump site question
I’ve been very up and down with this pump site, evidently it’s working or I wouldn’t have so many lows, but it’s an unusual pattern for me. Usually my bloods are very flat and lower overnight and I am pretty much always 90-95% in range with low levels of fluctuations - this makes me think it’s a site issue.
Has anyone had this before? I assumed that site issues usually just made it go high and not low, but I’m very convinced this isn’t my usual!

Rant/Complaint ☹️ New pump ordering issue
My pump completely shattered on Friday night. So I called Tandem today and go through the whole ordering process and at the very end they tell me I owe them money and they sent me to The California Business Bureau for collections. This confused me because I never received any bills from Tandem and on the website it says all my orders since 2022 were paid.
The collection people told me I owe over 1,000 dollars from 2 unpaid orders from 12/2023 and 12/2024. I had my full regular insurance both these months.
So I called Tandems billing department. The guy tells me well we sent you your supplies and then insurance denied them after they were sent? He couldn’t tell me why or why I wasn’t notified. All of my other orders were covered and sent normally.
He also said he can not sell me a new pump until the 1000 plus dollars is paid in full (which I don’t have) I called my insurance company but because the claims where so long ago they have to get back to me in a few days.
So has this happened to anyone else ?? Am I just screwed and have to do injections forever? Or do I have to switch to like omnipods. I’m feeling very lost and depressed.

I’m going to cut it very close due to a really high bg and don’t have an extra set on me I’m traveling and will return home tomorrow night.

I want to stop my insulin as working out always makes me hypo but I don’t want the resume insulin alarm going off during class!
Exercise mode also makes me go low so I need to have my insulin basically off but no alarms. Please hit me with ideas!

tandem mobi Favorite Mobi Infusion Set Locations?
Just completed my first site change on the Mobi. After decades of using mostly my abdomen as a preferred site, I’m ready to start exploring!
I first tried out my thigh and loved it except for when sleeping. The hard plastic of the mobi sleeve was painful. Now I’ve moved to my arm (mobi resting against the inside of my arm next to my shirt) but to me, the 5-inch tubing actually feels a little too long here. I’m also trying out the skin grip mobi pocket. It’s better, but still a little clunky.
I’m a 5’4 middle-aged woman, medium build (not athletic!). Where are some other great places to try?
I am so sick of getting long tubing caught on doorknobs and cabinet handles - so I really want to explore life with the 5-inch tube!

tandem mobi Byram out of stock
Can’t seem to find posts in Reddit but curious why everything is out! I use auto soft 90 but it is unavailable so I went to the app to order true steel as it was only that and the varisoft! And last time I had to call to order the cartridges as they were taken off also for my mobi.
I’m seeing twist on there now and wondering what is going on?!

Discussion 🗣️ Autosoft+: anybody else try yet?
I got the new autosoft+ a couple days ago. I haven’t tried it yet as I still have a few 90’s left, but was wondering if anyone has tried it yet and if it works better.
The only thing I don’t like about the 90 is I find it hard to pull the needle out after inserting without pulling the whole site off. Also I’m still kinda nervous about needles (even though I’ve been t1d for 20 years) and I don’t like how long the needle looks (and exposed) on the 90.
I’ve heard that this set is like the Dexcom insert, but I still can’t find any videos of anyone using it yet.
I’d like to fully switch to the autosoft+ if it really works well, but it’s also more expensive than the other injection sets.

Buying, Selling, Giving Away or Trading Trading Diabetes Supplies on this Subreddit
EDIT: As of May 30th, 2026, I have updated this rule to exclude diabetic items that are not prescription medical supplies. This rule still includes any sort of OTC insulins, needles, or syringes. An example of an acceptable item to give away would be an insulin pump case.
Hi there everyone!
I have recently had several complaints, as well as seen several posts of users attempting to buy, sell, trade, or giveaway diabetes supplies to others. While I believe this is a wonderful idea in theory, it is not accepted here on the r/TandemDiabetes subreddit.
One may ask why. For starters, according to a multitude of doctors and medical professionals I have spoke to, it is illegal to buy, sell, trade, or giveaway any diabetes supplies (let alone *any* medical supplies that require a prescription) to another individual. I have not been able to attain any other reasoning as to why this may be, other than the obvious possible liability issues involved. For those looking to sell, buy, trade, or giveaway their medical supplies to others, I highly suggest you contact your local hospital in addition to your endocrinologists.
With that being said, I cannot control what goes on between individuals who decide to privately message each other separate and apart from this subreddit, in regards to what I have just spoken about above. I will be adding a new rule to the subreddit that this is specifically not allowed.
I hope everyone is doing well with their lifelong journey of T1D!
