If you are in an area with good cell reception I do not believe there are issues.
It is in the fringe areas -- and I personally think the problem is with Apple.
My iPhone 6 Plus works as it used to.
My iPhone XS Max and XS are wonderfil cameras that sometimes act as phones.
If it is all Xfinity why is that?
Not willing to put all blame on Xfinity but Apple needs to step up and own the problem.
The problem is obviously not Apple. I brought my iPhone 6S to Xfinity Mobile from AT&T. I was using the same device the same Xfinity WiFi Router, the same Xfinity Internet service, and the same cell towers. The ONLY thing that has changed is I changed my cellular service to Xfinity Mobile from AT&T. Again, I have over 25 years of experience as a systems & networking technology consultant, with clients from single-person shops to Fortune 500 companies. Troubleshooting network issues is literally "what I do". If I leave my house and go to where the cell coverage is good, the problem completely disappears. I just happen to live in a relative dead zone for cellular service in my town, and if I want reliable cellular communications, I have to go sit by the window in my unheated, uncooled (but thankfully finished) attic. WiFi Calling using the same exact equipment and ISP worked flawlessly when I was directly on the AT&T network. I would lay good money that the problem is being caused by faulty carrier settings programming. Xfinity Mobile advertises that on their system, your phone will automatically transfer to their network of hotspots, which is obviously why their pricing is so cheap and why they require you to have an Xfinity service account before you can be an Xfinity Mobile customer. To my knowledge, no other virtual carrier is attempting to do this, swtiching between cell, home WiFi, and public hotspot on the fly.

Wow I am so glad I did more research about XM before jumping ship from ATT. Thank you all for letting us prospective customers know about this obviously big issue with especially Apple phones. I have an iphone Xs, but having the possibility of dropped calls like this is a big NONO, no matter how cheap they are offering it.
Sorry Comcast, but you just lost another customer who was willing to sign up for XM! Get your act together please!
Let me just say that my original grandfathered iPhone Unlimited Data Plan was costing me over $90/mo on AT&T, and even if I had switched to service with them equivalent to what I am now getting from Xfinity Mobile (essentially, 1 GB data/mo for $12), I'd be paying over $50/mo, and since I really only talk on the phone to a couple of people, mainly my mother, I can't say I'm entirely dissatisfied. However, this shouldn't be happening. I've just spent the past hour or so on the phone with a friend who is going through difficulties in her marriage and is in desperate need of emotional support, and our conversation dropped about ten times. Putting the phone in Airplane Mode does not cure the problem. I can sit here motionless, 2 metres away from my Xfinity WiFi router, with cellular data OFF and/or in Airplane Mode with Wifi and Bluetooth ON, and watch my phone retrain from XM Wifi to Xfinity Mobile, back and forth, every few minutes. And again, this *only* happens at home. It never happens once I leave the poor cell coverage that surrounds my home. The only thing I haven't tried is actually swapping out the Xfinity Wifi router for one of my old routers, to eliminate that piece of hardware at least from controlling my WiFi connection. But I haven't done that because I shouldn't have to. I'm paying an outrageous $10/mo to Xfinity for the use of this router, and I expect it to be worth more than simply buying a new upgraded router on my own every year.

I've had this same problem ever since I switched to XM from AT&T back in the Spring. It only happens at home. I'm a networking consultant, so i have a fair idea of what is causing the problem and how to fix it, but as fixing it requires XM to modify their carrier settings, there's nothing I can do about it. I have Xfinity cable Internet service at home and live in a shadow zone where I get poor cell coverage. There is an XM hotspot a couple of blocks away that works great. What causes this problem is that the XM carrier settings are constantly attempting to find the best route for your call/data, but when you are on WiFi Calling with a strong WiFi signal, the software is still attempting to second guess itself, and tries to hook to the cell network (and or the hotspot), which has a marginal signal, and the call drops. It then takes some time for the call routers to figure out where the heck your phone is on the network, before you can place or receive another call. Turning off cellular data sometimes helps, but not always. Reliability is worst in my house on the ground floor, and best in the attic, because the 16 feet of elevation difference means I get better cellular signal and a better shot at the XM hotspot down the street. However, I obviously cannot live in my attic or take every call in my attic. The WiFi router is in my bedroom on the second floor, and even though I am literally only 6 feet from the router, the phone still tries to switch to either the cell network or the XM hotspot. Again, in my situation, this problem doesn't happen anywhere other than at home, because I get great cell reception at my office and when I am downtown in my little burg. When I was on AT&T with the same iPhone 6S, and the same Xfinity Internet service with the same Xfinity WiFi router, I did not have this problem, because AT&T's carrier settings weren't trying to hunt between three different competing networks. It latched onto the WiFi and everything worked flawlessly. So, the bottom line is, XM has a bug in their carrier settings module that needs reprogramming, but this bug will only show up in a limited number of circumstances when the cell signal is marginal. PLEASE FIX THIS PROBLEM. It is extremely tedious to have calls drops ten times in the middle of a conversation, and even moreso to have them drop 9 times out of 10 just in answering the call.
