r/USMobile

Hi - I have had AT&T postpaid for a few years now and am tired of the high prices. My partner and I both want to get on a prepaid plan again. We are very rural. Five years ago I would have said we had to be on AT&T, but I'm on a Visible free trial and I'm finding that Verizon coverage is good in some spots where AT&T is nonexistent, but the reverse is true, too--in some places AT&T covers and Verizon has nothing, or AT&T is much faster. T-mobile is great where it exists, but coverage is much more sparse, so they aren't a real contender.

Couple of factors: we have two relatively new iPhones (13 and a 14 Pro) and plan to ditch them for Pixel 8s or 9s soon. And, we can't afford to do yearly right now.

So I was thinking about US Mobile's Unlimited Starter plan with the Multi-Network add-on. I don't fully understand deprioritized data even after reading a lot here. We barely use data--maybe 2GB a month each. We're almost always on Wifi or just getting texts or doing light surfing while on cellular. Is the QCI9 that comes with Starter going to be useless for us if we do need cellular when we're in the big city a few times a year?

Any other plans we should consider?

Thanks for your help.

Hey guys,

I recently jumped from T-Mobile ($85/mo) to US Mobile Unlimited Premium with the Multi-Network add-on on my iPhone 15 Pro Max. Even with the extra line, it's way cheaper than what I was paying before, but it's been a bit of a mixed bag.

In Fort Lauderdale, main T-Mobile gave me solid 5G everywhere. Switching to Light Speed, I immediately ran into dead spots indoors where signal dropped to zero bars or super sluggish data.

I tested Dark Star and Warp. Dark Star handles building walls better here, but outdoor signal feel a bit lower compared to what I had on T-Mobile. Right now I have Dark Star as primary data and Warp as secondary, using an Apple Shortcut to flip between them when things stall. While I can get signal in most places now, it kind of sucks going from a seamless setup to manually toggling lines just to stay connected.

Has anyone else switching from postpaid noticed worse indoor penetration or lower bar counts on these MVNO profiles? Is this just normal for the area, or could something be off with my eSIM/APN setup?

Also on the Apple Watch companion line: since US Mobile lets you activate the free watch plan on a Warp line (including a Warp Multi-Network secondary line), what's the cleanest way to set this up if my main ported number is sitting on Dark Star? Can I link the watch companion plan to the secondary Warp line while keeping Dark Star as my primary data line, or is it better to move the primary line to Warp and run Dark Star / light speed secondary?

Appreciate any insight!

I've been on Sprint/T-Mobile for a long time, and I'll port my phone line to US Mobile. Each month, I generally use about 5-10 GB of mobile data on my phone through the grandfathered Everything Data plan since I mainly use Wi-Fi. I use an unlocked Samsung Galaxy S23 Ultra.

How has US Mobile worked out for you all? Which of the 3 networks did you choose, and what plan would be best for me? Since my phone currently uses an eSIM, do I need to do anything before I port my number and get the US Mobile eSIM? I have never ported a phone line before, but I have the required information needed to process it.

Since US mobile already sells Starlink wifi , do you guys think they’ll also have them as a phone service provider ? 🤔

I have an S23. I contacted customer service just wanting to add a Dark Star Sim to my phone to complement my Warp Sim. I don't want two different lines and that would be confusing for people and messages. The person indicated that multi-network is adding a second line. Does anyone run two SIMs at the same time? If I'm in an area where Warp is better, then I want Warp and the same with Dark Star.

I want to start off by saying that this is not a complaint. I was on Chat with support last night for almost two hours trying to get this fixed and they were great. Since the cause never technically got fixed or figured out I'm genuinely just curious what could have happened.

I posted a couple of days ago that my Warp line would lose cell service for about 20 seconds at a time several times a day. And anytime I tried to make a phone call it immediately dropped the first time because I would have no signal all of a sudden. Sometimes I would have to attempt the call 3 or 4 times. Also when people were trying to call me they would get a network message that stated "We're sorry your call cannot be completed at this time". And sometimes that message would then direct them to call 611. I also had issues with data, I would be using the web browser or streaming music and then it would just go to no signal.

I knew it wasn't an issue with the phone mostly because of the network message people were getting when they tried to call me. If it was just the phone being broken then they would just get my voicemail. It also wasn't an issue with the local tower because this happened at home and work and my job is about 40 minutes away.

So I contacted US Mobile support through their chat last night. The person could not have been more patient and helpful. Honestly it was great dealing with them. We tried adding a new APN, resetting network settings on the phone, they tried something with the network on their end I guess but nothing worked. After two hours I was exhausted (it was now after midnight) and I finally asked what the rep what if you just teleport my line to Light Speed and I'll just change networks for now. So they did that and now everything is working great.

But I really just genuinely want to know what could have happened. I'm pretty confident that it's nothing that is US Mobile's fault and is an issue with my line on Verizon's network. But it happened so suddenly and after two full days of hoping it would fix itself I finally had to do something. I have elderly family members who don't text so they need to be able to reach me by phone.

Any ideas what could have happened? I've used the verizon Network with different MVNO's for several years before landing on US Mobile about two years ago and nothing like this has ever happened.

I also want to add that US Mobile's customer service is outstanding.

So I just switched from AT&T to US Mobile (southern Wisconsin). Really loved how easy it was! I selected Dark Star because I read that it would be using the AT&T network and it should pretty much be the same as what I had but now cheaper. All 4 lines when making calls would cut out and sounded robotic on all calls. I really wasn't expecting that and of course my wife was freaking out that I'd made a bad decision. Switched us to Warp (with some challenges) and so far so good. Why would my calls be so much worse initially if it was using the same towers?

I've been hearing a lot about the new and upcoming Starlink Mobile carrier that may be launching to become the next fourth US carrier.

My question is: Since US Mobile already has a relationship with AT&T, T-Mobile, and Verizon to power Dark Star, Light Speed, and Warp and already partners with Starlink to offer internet, does anyone think it might be possible that US Mobile could offer access to the Starlink Mobile network once it launches in the future?

Interesting to hear some thoughts.

A couple of months ago, we transferred 4 family lines from AT&T to US Mobile. The porting process was smooth, but we’re now running into a major international roaming issue.

When we were with AT&T, international travel (including to Brazil) was always seamless, which was a huge factor for us when choosing a carrier. My wife traveled to Brazil this week, and since arriving, she has been unable to receive incoming calls from the US consistently.

She reached out to US Mobile tech support, and they suggested manually switching between different local networks in Brazil (Vivo, Claro, TIM, etc.). She tried this, but the issue persists. With AT&T, connecting to local partner networks worked without any hitch, so we're trying to figure out why this is happening with US Mobile

I am heading to Brazil later this week to join her, and I urgently need reliable call reception for my US-based business while I'm away.

A few questions for the community / US Mobile team:

Has anyone experienced similar issues receiving US calls while roaming in South America?

Are there specific backend settings, provisioning updates, or APN configurations needed for smooth incoming voice calls in Brazil?

Which underlying network (Warp / Dark Star / Light Speed) handles international voice roaming best in this region?

Any advice, fixes, or help from the US Mobile mods/support team here would be greatly appreciated! Thanks in advance!

Hey everyone! I know there's already been a thread about this, I just wanted to provide additional confirmation for anyone considering it that you can buy a new iPhone and pay in monthly installments without actually activating with one of the major carriers. They do send you an unlocked phone, and the trick of continuing three times on the screen where it wants you to activate with one of the major carriers worked for me. Specifically, when I ordered mine, I chose the T-Mobile option, but I don't think it matters which you pick because I've seen comments from people who picked Verizon or AT&T. I sent my old iPhone to US Mobile as a trade in, because they offered more than Apple, and am waiting for that to be delivered and processed.

Ive been on AT&T for as long as I can remember (Palm Pre release) but found and have been following US Mobile for a few years and have been just truly amazed at their response to different things, the features they are continuously developing, and even the things they pre pre pre release and are Coming Soon™

I currently have 2 lines, one is my dogs iPhone (Boards often, visits my parents, etc) and has a Fi collar that works better with a device paired to it, and the other is my business line that I use a second eSIM in my locked att iPhone (Dark Star). With the release of the iPhone Duo, it’ll also be my first time purchasing a phone outright. The reason being, I have an amazingly great deal on a T-Mobile line and their speeds are 100x better than my AT&T speeds so I’m wanting to move my business number from us mobile to the other mvno to overwrite that number and use that on my duo for business number AND great data speeds, and finally port my main number of 15+ years from AT&T to US Mobile on Dark Star

My question is, which of my lines currently at US Mobile have some sort of “priority” qci locked in for free? Is that number specific or account? And finally, I have a trip planned to Mexico November 5-12. I’m wanting to get an annual plan that’s maybe mid tier because again I mainly want to use that line as my main voice / text number and not so much data, but would like to have a good decent data speeds in Mexico on it. Any suggestions? Should I port now before the phone launches? Which carrier has the best roaming in CDMX? I hope to get in touch with an agent - y’all are always very helpful.

I’m kind of scatter brain and love this community so please don’t attack me y’all I’m just a dude from Kansas with severe ADHD.

I currently have two lines with US Mobile, one of which are covered by a 12-month free multi-line promotion following the activation of an iPhone 18 Pro Max. Having prepaid for 12 months of the Unlimited Premium plan during last year's Black Friday sale, I have approximately one month of service remaining. Additionally, I possess an inactive free line provided by AirTalk due to my participation in the SNAP/Medicaid program.

I am weighing two options:

First, porting my primary number to Mint Mobile to take advantage of their $10/six-month promotion, while transitioning my secondary, work-related line to AirTalk, as it requires only voice capabilities rather than data. I recognize that this approach would forfeit the remaining 12 months of the second-line promotion with US Mobile.

Alternatively, I am considering renewing my US Mobile service under the multi-line promotion for the upcoming year and downgrading to the Starter plan at $25 per month. Which of these strategies would you recommend?

I guess I'm just wanting some group input / therapy. Right now I have 4 unlimited lines on tmobile under a 4 for $100 plan, which in reality is $124.81 because there's basically $25 in fees and taxes added every month. We have a 5th line on tello for $8 a month at like 2G of data for our 13 year old. All phones are paid off except mine which is an iphone 17 on payment 11 out of 24 I think. $400ish left. Coverage is good in our area for any major carrier, att, verizon, tmobile is all fine here. So I've been looking at usmobile thinking it could save us money, right? I want unlimited everything but highest priority data isn't the biggest issue as long as it's not incredibly slow. And our rural area doesn't seem congested from what I've seen. Our 4 for 100 hasn't been slow at all on tmobile and from what I can tell, wouldn't be with att or verizon either. so what do you guys think? Unlimited Starter on darkstar? If I wanted to try things out, could I pay mine off and just move it first to see how it goes, and then move the others later?

I'm currently on Unlimited Premium with Dark Star, and I'll be in London and Dublin later this fall, including some time in the surrounding areas.

I'm considering switching to Warp for Apple Watch support, but I'd love to hear how the phone roaming compares before I make the move.

If you've used either network there recently, how was it for everyday stuff like maps, browsing, calls and texts? Did it connect smoothly when you landed, or did you have to fiddle with settings or manually choose a network? I'm especially curious whether things changed once you got outside the city centers.

If you've tried both, which would you pick for this trip? Also happy to hear about any Apple Watch or roaming gotchas I should factor into the decision.
