One time, I needed this. I lost my phone with a physical SIM card and needed a replacement that day. Now I'm trying to remember the eSIM transfer flow to know if this is still an issue.

But also, which MVNO should you go to? Carriers supposedly prioritize their own customers, so it feels a bit like running on spot instances.

[karlgkk]

> Carriers supposedly prioritize their own customers

They explicitly do, even among their own customers and plans. If you Google the carrier name plus QCI, you’ll find tables where people have documented, which plans are in which priority group

[wolvoleo]

Yes. Basically: you get what you pay for.

I've also seen MVNOs be denied frequency bands or cells that were in the highest demand, leading to worse connectivity despite being on the same network.

If you are so paranoid, just get multiple SIMs? Most phones support that these days, especially multiple eSIM. And the plans are really cheap (at least where I live).

Mint (T-Mobile MVNO) has been great for me, $20/month/line and my one experience with international travel was good ($20 for 10 days). I used to be on Verizon and the quality of service doesn’t seem any worse while the price is dramatically lower.

[SapporoChris]

Mint works well until it doesn't. I travel a lot and use voice over ip(VoIP). One day I called and got an automated message that my account needed funds. It didn't, my annual payment was months away.

My call to tech support was the generic worst. He insisted there was trouble with my current cell tower and I should reboot my phone. (ignoring the fact that I was able to get automated message). I explained I was using voice over ip, but the tech support didn't seem to understand that technology. Perhaps it wasn't in the script. I was on the call for about 30 minutes and eventually gave up. Phone started working about eight hours later.

Previous issue was with their roaming in foreign countries, however with VoIP that hasn't been an issue for years. So, a couple problems in about eight years. I rank them as one of the best among the terrible options.

[ericpauley]

Insisting on saying VoIP to the Mint rep instead of WiFi Calling (the term used by Apple, Google, Mint, and practically everyone else) is asking for a bad time.

[gzread]

Indeed. To a carrier, VoIP means WhatsApp, Discord, Google Meet.

US Mobile gets you QCI8 (same priority as Verizon postpaid) when you're on the Verizon network with a 5G device, and they let you pay for QCI8 on AT&T.

[mortenjorck]

USM is the only MVNO I've seen that actually advertises QCI tiers. I had to look the term up when I was initially considering them, as I'd never even encountered it before. It was a major factor in finally feeling confident I wouldn't be giving up too much by leaving AT&T.

eSIM transfers are an absolute nightmare on T-Mobile. I recently did two of them and both times, the transfer started but never finished, so I ended up with no service on either device. That means no ability to call their support line and no ability to receive the confirmation SMS they use to verify you are the correct person. They also immediately permanently nuke your physical SIM card so the only way to go back to sanity is to purchase another $10 physical sim card or get one of the physical sim cards that you load eSIMs onto (I did the latter so it won't self-destruct every time I do a transfer).

1. They only do transfers through their native app, not on their website. To log in to their native app, they will do SMS verification. So I sure hope you are still logged in before they lose your eSIM and leave you with no service at all.

2. If you are able to get into their native app so you can access their tech support, their AI chatbot will flat-out lie to you and tell you that T-Mobile cannot send you a QR code to download your eSIM (even though T-Mobile's own website states that they can). If you ask politely for a human, it will resist. I've found "connect me to a human you worthless fucking bot" is the secret passcode to get a real human.

3. If you request they send you a QR code, some of their support staff will ignore that request and still try to initiate the transfer through their app, so clearly requesting the QR code is not a common procedure.

4. When you request a QR code, even though you provide the EID, they will ask for an IMEI number. They then generate the QR code for whatever EID they have associated with your IMEI number in their database, completely ignoring the EID number you sent them. They did this to me _three_ times. The only way I managed to break the cycle was I sent them an IMEI number for a phone that was never on their network so they'd finally listen to me when I told them my EID number.

I'm never buying a phone without a physical sim card slot again. There's nothing wrong with the eSIM technology but the carriers have decided to make it as miserable as possible. The hardest part about transferring a physical SIM is finding a paperclip.

[dghlsakjg]

Wow. That really sucks.

As a counterpoint (not sure if this was t-mobile, apple, or both), I just upgraded from an iPhone 11 with physical sim, to iPhone 17 with esim.

All I had to do was hold the new phone next to the old one, and it just transferred the line over and deactivated the old sim automatically. I wasn't even in the US (so not even on their network), and it was stupidly seamless.

It sounds like t-mobile support has gone downhill. Last time I had to contact support was 2020, and it was really easy back then. I rarely had to wait more than 5 minutes to get a human, and I once had an issue escalated to the "executive resolutions" team and resolved to my satisfaction the day it was opened.

[joecool1029]

Apple’s system mostly works. If you need to reissue an esim without being able to transfer from an existing device on T-Mobile though need to either call in and give imei or get past the chatbot and there’s a page text support can give you to enter details. I was never able to successfully use the shit t-life app’s manage esim option.

[craftkiller]

> Last time I had to contact support was 2020, and it was really easy back then

Looks like that was 2 CEOs ago (Mike Sievert in 2020 and Srini Gopalan in 2025) so one of them probably bears the responsibility for this decline.

2024 might have been the start of forcing us to fight with toasters: https://www.t-mobile.com/news/business/t-mobile-launches-int...

and 2024 seems to also be when they locked down their esim transfer process: https://www.reddit.com/r/tmobile/comments/1cnphk4/android_es...

So I guess Mike Sievert drove t-mobile into the ground?

[sagarm]

You were on the happy path. I just had to get involved for a family member that broke their Apple phone and couldn't get their SIM transferred. Even after adding them as an authorized user under duress, they had to physically go to a T-Mobile store to get their phone on the network.

[joecool1029]

> When you request a QR code, even though you provide the EID, they will ask for an IMEI number.

Everything else you say is accurate but they do not require this, T-Mobile is the only major in the US that doesn’t match EID to IMEI. I know because I use a removable esim (esim.me) euicc with multiple phones. I have to read the super long eid off to support to activate it. I cannot activate service on this card with verizon or at&t as its eid doesn’t match to an imei for them.

[craftkiller]

I think you're misunderstanding. I'm not saying T-Mobile locks the EID and IMEI together. I'm saying their tech support will completely ignore any EID you send them and instead look up an EID in their database based on the IMEI you send them. If you manage to convince the tech support to actually listen to you and use the correct EID then yes, everything will work out fine and you'll be able to move the card across devices.

I was also using a removable esim (from jmp.chat) and they did this to me three times. Each time it went like this:

> Me: Please send me a QR code to download my esim. My EID is XXXXXXXX

> Them: Thanks for providing your EID, please send me your IMEI (the first time this was just a plain message, the 2nd and 3rd time they sent me a link to a form to submit my IMEI to them)

> Me: <sends them my IMEI>

<at this point, the first two representatives initiated a transfer through their app and told me to wait 2 hours and then the transfer would finish. I told them whatever automatic transfer they just initiated will not work and they _need_ to send me the QR code.>

> Them: What is your e-mail address

> Me: My e-mail address is [e-mail]

and then they'd send me a QR code. I'd then attempt to download it to my jmp.chat esim and I'd get an error that the EID was incorrect. Then, I'd try using the QR code to activate the built-in eSIM on the phone with the IMEI that I sent them, and it would work, proving that they were looking up the EID for the IMEI that I sent them rather than paying attention to the EID that I started the chat with.

The 4th and final time, I sent them my Librem 5's IMEI which had never been on T-Mobile and does not support eSIM. They told me that the phone was carrier locked, I assured them it wasn't and explicitly told them "it is important the QR code is for the EID I provided you. The past representatives have ignored that, leading to the error message <pasted the error from EasyLPAC's logs that was something like EID is incorrect>". THAT time they finally listened and sent a QR code for the correct EID, which let me download the eSIM to my jmp.chat card. At that point I was able to move the card across devices without issue.

[joecool1029]

Apologies on getting back late but… I’ve never had that experience. Historically I would call during day and get someone stateside. They would ask for IMEI and I would say ‘it’s not in your db but EID works’ and then they’d let me read that off, never an issue. Now I use the chat, it’s faster since they just give a portal link you drop the details to.

Call during day or you get the Philippines and they don’t understand specific requests like this as well. If you must do it at night use the chat route.

Ive been happy with US mobile - you can actually switch between their VZ backed network or their ATT backed network.

[yencabulator]

Google Fi punches above its weight class as an MVNO. It's apparently often even prioritized better than many telcos' own cheap plans.

(Obvious downside: It's Google.)

[mey]

Personally switched from VZW to Google Fi. It's on TMOs network. As you can imagine, when engaging with Google's support was hilarious when there was something I needed, but overall I don't miss Verizon and pay drastically less.

[laurencerowe]

Is Google Fi particularly cheap? Their normal prices seem to start at $35/month for 30GB of data which is more than Verizon's Visible plans at $25/month. (The current 50% off offer on Google Fi does seem a good deal though.)

I ended up switching to Mobile-X since I'm on wifi so much I only use a few gigs of data a month. $2/month + $1.90/GB vs Google Fi's flexible plan of $20/month + $10/GB.

[verdverm]

My Google Fi is $20/m for connectivity and then $0.01/Mb until I hit 6Gb ($80) at which point everything after is no cost. Most of my data is on wifi, so my bill rarely goes above $25

[laurencerowe]

I usually end up paying about $5/month, though that is a data only plan as I just use Google Voice for calls and use maybe a couple of gigs of data.

Having moved here from the UK where I was used to cheap mobile plans I just grate at how extortionate they are in the US.

[Sohcahtoa82]

> Is Google Fi particularly cheap?

If you travel internationally, they're really cheap relative to everyone else who will charge you absolutely ridiculous roaming fees.

[laurencerowe]

I just buy local eSIM's online when I go abroad now. Lycamobile is usually good around Europe if you land in a country with them. Their UK and Portugal subsidiaries are £5 or €4 / month with 30-50GB in country including 12GB roaming in other European countries. Order before you go and get the eSIM QR code by email. But you must be in the appropriate country to activate.

The Google Fi plans with roaming are either $65/month (100GB) or $20/month + $10/GB. I often end up using quite a bit of data abroad.

[rootusrootus]

For those of us who have crappy coverage with TMO, Verizon themselves offer a much better alternative to their postpaid service, called Visible. It's pretty hilarious how much better of an experience it is, and you are on the same network.

[throwaway27448]

I haven't had any issues with tmobile coverage (that wasn't also a problem with verizon) in well over a decade now. Hell it even worked well in the dense hilly jungles of burundi. Verizon customer service was so bad before I switched I swore them off for life....

The single place I noticed verizon gets coverage and tmobile doesn't is three levels underground in a concrete parking garage.

[laurencerowe]

Coverage is very specific to your situation. I've had basically no coverage on Verizon in offices in the Bay Area where T-mobile worked fine while colleagues could only get Verizon at home.

[axus]

I was able to transfer eSIM for a lost phone using their website, I think the online carrier had run into that issue before.

[slumberlust]

They're all fungible if you aren't addicted to your phone.
