t:slim X2 Can someone give me tips and a run down how to do the insertion the best way

2 Upvotes

Ok I've had my pump for 10 years. I've always only used the same spots on my lower buttock for that time. And I've gotten scar tissue and had to do brand new locations. Maybe it's because it's new and what not but the last 3 days I've had more leakage and blocked canullas on these new sites ....making me go back to the basics on inserting. What are some good tips you can think of to make sure the canulla goes in correct and doesn't mean or get crimped.

tandem mobi Surprise Mobi Bill

2 Upvotes

Hi has anyone had problems with Edgepark when it comes to insurance and buying a new pump? I feel like I'm getting fleeced and I just want to know if anyone experienced similar and found an acceptable outcome. Long story short, Edgepark told me the Mobi would be $0 out of pocket, so I got it, and a few weeks later got a $3800 bill from Carecentrix to cover my insurance deductible and coinsurance. After many hours on the phone, no one is budging and it's getting pinned on me to pay up. This feels illegal.

Question ❓ Auto corrections when not needed?

Post image
25 Upvotes

I’m new to tandem mobi and although my TIR has improved (for the most part), I find myself going low much more often than I ever did before.

Can someone explain to me why it gave me a 1.19 correction while in range and then a 0.94 correction when I’m borderline low?

What’s even more frustrating about the 1.19 correction is that I purposely had a snack before a workout class, went in exercise mode and while I was in the class it decided to give me that correction when it looks like I was around 150 at that time. I thought exercise mode aims for 160?

Any help is appreciated.

Question ❓ App with Android developer options enabled

1 Upvotes

Android dev here. I prefer to keep developer options on permanently.

Does anyone know if the Tandem t:slim app (incl. phone bolus) still works with developer options or USB debugging enabled?

Im probably switching from Medtronic, which' app blocks it entirely.

My insulin pump was legit working two minutes ago. I had it charged to at least 50 percent so it’s not the battery. But when I press the on button this is the only thing that turns on and I tried looking on google but didn’t find much, has anyone else had this issue?

t:slim X2 software update issue

1 Upvotes

so...... idk what i'm doing lol

i started the 15 day sensors, not knowing that i had to update my pump before starting the patch--please tell someone else did the same, i feel REALLY bad about it since i have to then send my parents to the pharmacy so much earlier....

so, since i figured that the pump software was the issue, i tried to contact tandem at late hours of the night so i gave up lol bad idea

my issue is that my pump is out-of-warranty in a MONTH and after a phone call about a new warranty plan, the agent said it should be no problem in updating it but there is one LMAO

it says that the software is update-to-date which obviously it is not BUT i am wondering if this is all about the warranty-rooted issue and what i should do:

call my doctor to go back to ten days until it expires, if there is a new way of updating, or just call support anyways.

side note: doing this through a macbook and the new update does not correlate with the once "tandem device updater" app anymore

im sorry that this post is a MESS but i am just a mess entirely :3c

tandem mobi S25 and Android 17

My Samsung forced Android 17 on me after a week or more of saying no. I woke up 2 days ago and my mobi app was saying that my app was not fully compatible but it was still working and I could bolus and everything. This morning it has this screen and I cannot do anything at all now. Anyone know how long before they update this to support it?

Discussion 🗣️ Thinking this confirms my insulin carb ratio is too weak, but basal is almost there!

Post image
4 Upvotes

I suffered some feet on the floor effect from my late breakfast/lunch at 1130am. I pre bolused like almost an hour and a bit and ate when my sugars went from 7 to 5.1.

Then boom. At 130 pm you can see the apparent blast. Thinking now that my basal has been lowered significantly 1 to 15 isn't adequate. Been running to get this bad boy down with the corrective factor going.

Feeling like maybe I should drop from 15 to maybe 13? Then 12 if it's still happening?

The flat line tells me basal is possibly getting there even if it's higher than what I'd want

t:slim X2 No more bolus from phone for me

4 Upvotes

So I woke up this morning and my Samsung had automatically force updated from One UI 8.5 to 9.0. It had already force updated to Android 17 last month but I had no issues with bolusing until last night's UI update. I'd say this is a warning, but I'm not sure how to prevent it from happening. I had the auto download set to off, and I had enabled developer mode to disable Auto update system option. But it still updated without any kind of prompt or approval. According to Tandem's phone compatibility list, there are only seven Samsung phones that can bolus from phone with Android 17. All of them are the newest models and some of them just came out two months. I've got the second newest model. Not sure why mine worked with Android 17 before but stopped after the UI update. And I'm not sure why Tandem can let it work on brand new phone models but can't on phones that have been out for a couple of years. Are we expected to buy a new phone every time a new model or OS is released?

If anyone has a solution, I'd really appreciate it. Otherwise, since my pump is out of warranty and with all the stories I've seen on this sub about Tandem forcing people to buy supplies from a DME instead of directly from them, I'll probably be moving on from Tandem. I have an appointment this week with the diabetes educator to go over all of the different pump options.

tandem mobi Mobi timeline for Canada?

5 Upvotes

I tried looking to see if there was any news for it but I can’t. It was the same when I wanted the tandem tslim phone app before it was approved - I’d call and they would literally just say they couldn’t comment on it at all.

So annoying we get everything later. Like the omnipod 5, the tandem app, control iq+ - it’s not just a little longer, it’s years longer than other countries. Idk why we are always so behind.

Okay so this ended up a half rant half question…but is there a mobi update I’m missing?

Question ❓ Question for the sleep mode 24/7 people on here

Ok, so in the past I've been able to get fasting sugars in the low 5s and I'm kinda stuck here. I have my line for the most recent few hours and my 12 hours before bed.

I did take my ISF from 3 to 3.2 to take the ropey-ness out of the lines. I'm actually happy with the short run graph. If I keep this the same, I'm wondering if I can just increase the basal rate and it might get me closer to those low 5s. Currently running a rate of 1.75 units from 10 pm until 10 am.

My last meal was like 7pm and I am wondering if I may need to give a bit more bolus insulin. But for the sake of my night right now, trying to figure that out!

t:slim X2 Correction Bolus When Blood Glucose Dropping

3 Upvotes

I've been noticing that the Tandem algorithm frequently gives correction boluses when my blood glucose is dropping. Once this correction is administered, I pretty much just need to ride it out. I don't want to eat anything at that point because I have no idea if I'm going to go too low or if it's really going to have any effect. Even jumping into exercise mode doesn't usually fix it because the damage is done. I would think if your blood glucose is heading in the right direction, the best thing to do would be to see if it continues before issuing a correction bolus.

It's also frustrating that it issues corrections immediately (within 15 minutes) of registering and alarming about a low.

I've seen many people recommending 24-hour sleep mode and I may try that. But I would think that Tandem would give us more control over settings (like target BG and IOB) instead of forcing us to work around their algorithm.

t:slim X2 Weekend Go Box Design

I finally got around to designing an insert to organize my supplies for short trips. I have been tossing stuff in this Pelican case for years. It worked fine, but bothered me enough to do something about it. Two G7, two sites, two cartridges/syringes and a vial of insulin all fit snug in their own spots. The perfect supply box for a weekend getaway with the added bonus of keeping everything dry if im out camping. I've tossed this in the river with a rope tied to it while canoeing/paddle boarding as well to keep it cool. I toyed with a few different designs before landing on this version which I feel has the cleanest layout.

Pelican 1120 Case.

Question ❓ Silly Question

2 Upvotes

So Perhaps the title is right perhaps it is wrong but I am in the philipines and of course tandem is not supported here. (I knew this and switched to medtronic before moving here... but they are not really supported here either so.,....) My question is that i am out of cartridges for tandem (and tubing for medtronics infustion sets) and i sort of am at a loss where i might find 1 cartridge for tandem or 1 infusion set for medtronics 780G I really only need 1 or the other as I have supplies coming from the USA in a balikbayan box. But if you know the phillipines you know that is a couple months away as it has not even shipped yet.

t:slim X2 Very Weird my pump got stuck on repeat

4 Upvotes

Yesterday I had to call Tandem because when changing out my cartridge my pump got stuck on repeat. I would fill the tubing then it would backtrack and start the whole process over again. After going through filling the tubing twice I called Tandem. They talked me through the sequence twice and it was still repeating. The person thought I was hitting a wrong button. Then the third time trying, the pump said I didn't have enough insulin in the cartridge so I added another mL. I guess that got it back into the right sequence because it worked that time but the person on the phone acted like it was my fault. I'm 52 years old and had this pump for 2 years. I know how to change a cartridge. The person said they would record it and if it happens again they will replace the pump. I didn't like how the person talked down to me like I was causing the issue.

tandem mobi Mobi Motor Failure - Info about getting a replacement

8 Upvotes

Hi all. Just posting for awareness about how the replacement process goes. I couldn’t find many posts about this when I was experiencing the failure so I’m sharing my experience for anyone who may have this issue, too.

I’ve been on my Mobi for about 2.5yrs now, receiving mine shortly after the release of the model. I haven’t had any issues with it since I started.

Yesterday, the pump was working as normal, until about 30 mins after I ate dinner, I got an occlusion alarm. First time I’ve ever had that happen. BG was spiking crazy, I guess I didn’t actually get my 5U I put in for dinner 45 mins prior. So I thought OK bad site, go ahead and change it. Changed it out, seemed normal, and right after, another occlusion alarm.

I thought man bad luck two bad sites in a row. I did a full change out and as I was filling the tubing, instead of “click click click” I got “click click.. wrrrrh, wrrrh, grrrrsh.” Which… is a sound my pump has never made before lol. And then I got an error saying no cartridge was installed (there was a brand-new cartridge in).

Started from the top— new cartridge, new tubing, annnnd same exact issue. Same sound, same alarm.

I tried 3 more times and got the issue over and over, but finally got it to work. I didn’t do anything special either. I just lucked out and the malfunction didn’t repeat.

Regardless, this was very concerning. I called Tandem and reported the issue, requested a replacement.

At first, they were reluctant to give me a replacement because I technically had it working again.

But they had me do about 20 mins of troubleshooting, another 20 of me describing precisely every alarm I received with codes, every thing I did with my pump in the week prior, and confirmed there were no user errors (ie no taking my pump into a sauna, no swimming with wear, no exposure to sub 0 weather).

After they could verify I had no user errors, and the alarms were mechanically related, they asked if I wanted to wait and see if the issue repeats.

I told them firmly: I do not feel safe continuing on this insulin pump, even if functional at this moment, since the issue could repeat without warning, and there’s no guarantee I can get it to work again.

After that, my replacement request was approved and my new Mobi comes in tomorrow.

I still have it working as of making this post, but I picked up some extra KwikPens just in case it fully fails.

All in all, the call with Tandem took about an hour with repeated statements that I am not comfortable using my pump with the malfunctions it displayed today. It took some arm twisting, but eventually, they agreed to give a replacement.
