I just unboxed my new Mobi pump today and was completely stunned by the 1" thick manual and the length of the online training. I'm just having a hard time getting my head around the plethora of details. And I'm NOT NEW. I have been on various insulin pumps since 1999 and have been using CGM for at least five years.

For one thing, maybe it is a mistake to change both pump and CGM at the same time? I can't even find a YouTube video about doing so. I assume that I should change the CGM over first--but I'm not sure and can't find anything about that online. Would you all recommend that I just change the pump out while using the G6 and then wait a few days to change to the G7? Or vice versa?

And Tandem does not really speak to using both apps--the one for Dexcom along with the one for the Mobi. I need to do that because my husband wants to get notified of any bad lows while he is away. How do you coordinate things between the two apps? Do you enter Dexcom information into the Dexcom app first or into the Tandem app?

Thanks for any advice. It's embarrassing for me to ask such basic questions, but maybe I am getting senile in my old age!

I got a pump because I'm pregnant, but I'm not planning on using it postpartum. I can't fathom just throwing it away, considering how much it costs. What do people do with their pumps when they're no longer using them?

Woke up to a perfect 80… but I guess mobi decided that was too close for comfort and suspended my basal for an hour. No food and now I’m 180. I am most insulin resistant in the morning, so I wish I could set mobi not to suspend during that time. Anyone else?

I am using a Tandem T slim. My pump goes out of warranty on August 29th.

The clip on my case broke, and I am wondering if anyone has a case or clip they would like to get rid of.

I will happily reimburse shipping costs.

I always get an occlusion alarm after a site change. When I change the set after the occlusion, everything is fine. I never get a second occlusion. Why do I always get one after the first site change? It’s like I know I’ll 100% get an occlusion every time I change the set after 3 days.

Will I be able to play gta 6 on my Tslim pump?

The warranty for my TSlim X2 expired mid-June and I'm in the process of getting a new one (another X2). Today my endo's office called and said that my health insurance (same plan I've had for many years) is requiring a c-peptide test before they'll approve a new one. I've had T1D for 26 years, so this seems unnecessary to say the least. Anyone else have this experience?

Long post! Help! I am so frustrated. I had been on an old school Medtronic pump for so many years. I finally decided to switch to a new pump to get my sugars under better control. I switched to the Mobi. Does anyone ever get any sleep with this thing? This is not sustainable. My blood sugar was low all night (in sleep mode). Sometimes I don’t think it’s realistic how low they expect our blood sugar to be. I have done everything right that they asked me to do and it woke me up low 2 times. I finally got to sleep at 2 am after eating 3 packs of fruit snacks and a pack of peanut butter crackers and woke up low again at 7 am. I ate a pack of fruit snacks for the 7:00 low because I desperately wanted to go back to sleep, then it woke me up 30 minutes later saying high. Please tell me this gets better. I want better blood sugar control, but not at the cost of my sleep and sanity!

Hi all!

I have been on the Tandem Mobi for 2 years. I was wondering if anyone has had success with billing a new phone through DME and having insurance cover it? Basically, my thought was have my doctor prescribe a phone since it is required to use my pump and then running it through DME? Not sure if that’s possible.

I'm considering a pump for the first time in my life and the Tobi checks all the boxes for me (7-Days of use, small form factor, waterproof but removable as well, integrates with Freestyle Libre 3 Plus). Is it still on track for a general release in the 3rd or 4th quarter of 2026?

I had read that Tandem may roll out the Tobi in controlled phases, is there any way to get on an "interested parties" list for the first phase?

Hi there team,

Im fresh to the pump never used one before but have always used a dexcom g7.

Im having non stop issues with the pump lossing signal with the cgm even though they are literally right there and iv followed there recommendation of opposite side to my cgm.

Iv even tried taking it out of the case, changing cgm. Putting it right next to the cgm and im about to yank this POS out and go back to manual dose as im having more time out of range then before to the absolute worst level ever.

Is there any solution or is this just how these are?

I should mention im using an fully updated Samsung s24 ultra no wifi but that shouldn't be a factor to my knowledge but open to ideas here

Just looking for advice really. I double checked the code but it's all correct. However nothing after the code in the CGM info section is showing up.

This is my first time using the G7 but I followed the guide

Ended up switching it out. Just wanted to say thanks.
