Does anyone have any experience with esim? I was using esim with Verizon for about a month and a half and I have to say that my service sucked. I was having issues with keeping service, it would randomly drop, my internet speeds were ranging 0.5-1 mb/sec, dropped calls, ect...
I ended up going with physical sim with Verizon and it was like a 180 degree turn, I don't have service being dropped, my internet ranges 25-100mb/sec, no dropped calls, you get the picture.
But I ask if anyone else has had that problem? I did research and found that due to the antenna array in the majority of the phones will have a decrease in service quality when you have both esim/sim activated at once, but I only had esim running with the physical sim empty.
Any suggestions?
Thank you,

Negative experience with an iPhone 11 soured interest in messing with esims. Daughter's phone; attempted to migrate long standing Verizon service to esim so physical slot could be used for regional carriers during a overseas trip.
Transition was a nightmare; lost service for 12 hours on two occasions while still in the US, both of which required intervention by Verizon support due to provisioning issues. Hoping it was a device issue made another attempt on a XR; that failed entirely. Dumped Verizon on that line and migrated to Google Fi (physical card). Cut over instantly and worked flawlessly through 7 Western European countries. Never looked back.
I wonder how much was due to Verizon provisioning vs. using esim. Reported experiences vary widely with final results largely polarized. Not worth the hassle IMO, especially when transitioning to a new phone. Card transfers seem to work flawlessly (at least with Verizon) and allow instant reversion to another device.
At least I am not the only person. So many people saying it is in my head and that esim is superior.... But regardless, wish it wasn't a problem.
Thank you.

esim was the only way to get service until I got a new sim and it worked pretty flawlessly for me.
Mine works just fine.
Phisical sim on Vodafone and e-sim on Orange.

Ok, here's the deal. My Girlfriend is going to Germany in less than a month for 2 weeks with her school. I'm the paranoid type, and seeing the movie Taken has not parlayed my fears one bit.
I want her to have a cell phone while she's there, but also want something that can run Mologogo or another similar GPS tracking program. I'm not infringing on her privacy and she has control on when to turn on the program (unless there's a way to have it run in the background secretly... just kidding... but seriously)
So, I'm looking at 2 options. 1) Get her current plan upgraded for international for this month while she's away. Not the best prices, but it's simple. or 2) The better plan is to find a local carrier (vodafone, cello, etc.) and have her swap out the Sim on a phone I get here....
I have NO idea how cell service works across the pond and I've been getting conflicting stuff left and right. Basically, if you've done option 2 before, just let me know what you did, and I'll probably do that. The GPS tracking is NOT a priority, I just want her to have a phone there.
thanks
first you need a Quadband phone then some trust
When traveling internationally you need an UNLOCKED tri or quadband GSM phone. My favorite travel work horse is a Treo 750v. If receiving calls to your current USA cell number is a priority simply add international calling to your current account (if GSM carrier like At&t) and it is enabled automaticly on your sim card. Non GSM carriers like Sprint will issue you a SIM card to put in your phone while away. Rates are high for this convenience, expect to pay around $1.75 to $1.99 per minute or more for USA calls. Data support is sometimes available, expensive or other times data is non existant.
Once abroad you can purchase a local SIM card that gives you a local number in the foreign country and now you must either use a prepaid phone phone card (excellent for short term) or subscribe to a monthly billing account (good for long term) to have usable calling minutes on the phone. I like the $10 cards and most of them can be re-charged using a credit card. Rates are cheaper to the USA, around $1.40. Unlike the USA data rates are expensive, often billed per 1k! This is ok to check email occaisionally but forget about browsing the net for hours. The negative of all this is you have to switch SIM cards depending on if you want to receive USA inbound calls or make calls to the USA and check you voicemail. Now you know why there are "dual sim" made in china phones on ebay.
Recent phones now offer WIFI so it is possible to use skype for calls if you have an account and find an open WIFI network. I have accomplised this on my Treo 800w. There can be reduced call quality on WIFI depending on available bandwidth.
Tracking a person's phone would either rely on a USA based service that unlikely functions abroad or raw GSM data from foreign towers that may or may not yield valid data.
Seriously re-examine your need to track someone and the level of your trust. If this is a person you want in your life then allow them the freedom to be away and miss your quality companionship. If they really care for you then you have nothing to worry or track about.
Actually, the tracking is an on-board Java applet that accesses the Phone's internal GPS module and sends the coordinates to an off-site server for viewing on PCs, etc. www.Mologogo.com if you're interested. Yes, I do have trust issues, but not with her, more of other people. Just because you're not paranoid doesn't mean they're not out to get you. I always err on the side of over-preparedness... worst-case-scenario type of thing.
Yes, my plan is to use the "local sim card installed on an unlocked tri/quad-band cell phone bought locally here in the US" method. However, I've heard of companies that actually ship those sims to you ahead of time, so that you can do all the set-up here, instead of fiddling with it in the middle of your already hectic trip.
My thing too is One or both of us will be calling international. It would probably be cheaper for me to use a land-line and a phone card to call her local german number, no? Or maybe even use Skype's Skype-out service (which is basically VoIP-to-Landline/Cell service)
But again, Which company do I use. I know the mechanics, I need the specifics.
Oh, and thanks for the heads-up on the data plan, ix-nay on that on account of costs. I think I'll just spring for a can of pepper-spray instead of gps tracking.
I'm posting here on behalf of a friend because I've tried everything I think I can do to help, but to no avail. I'll try to make this quick.
My friend bought a Galaxy Nexus LTE in December and it worked great for a few weeks, until the vibrator in the phone broke - he took it to a VZW store and they replaced it for him.
Upon receiving the replacement phone, he was having trouble with LTE staying connected. It would continuously drop and instead of falling back to 3G, it says he has no signal - signal indicator in settings displays a red bar (i.e. no coverage).
He took it back to VZW and they tried his SIM card in an employees phone - same issue happened to that phone. They then tried his SIM in a new phone off the shelf, same thing happened again.
Verizon is saying it's an issue with something at the account level, but I've encouraged him to go in and complain until they give him another replacement, just in case. However, it's very odd that his SIM card in three different GNex devices produces the same issue, even though his first one worked great. They have said that a future software update would fix this.
The other day I installed the leaked 4.0.4 update on his phone to see if the new radios would work, but the same issue kept happening. So I reverted him back to 4.0.2 so he could take his phone back to Verizon and beg for another replacement. Unfortunately I forgot to re-lock his phone so I still have to do that before he takes it in.
Has anyone ever heard of this before? It seems so odd that his SIM card would do this, but I still think that Verizon owes him another replacement device since he has a phone that isn't working like it should. He's getting a big discount on his family plan but he'd prefer to have LTE on his new phone.
I would love your thoughts - this just doesn't make sense to us. Any suggestions other than replacing the phone again? It sounds like VZW doesn't want to do that for him so it might be easier to fix it another way.
Can't speak for Verizon itself, but I have been through several SIM cards now on Telstra. Same issue, all of a sudden they are unable to pick up signal at all. Seems the pre-paid cards are more susceptible.
I'd ask for a replacement SIM, as opposed to a replacement phone as it's been proved the issue exists on multiple handsets already. If a new SIM doesn't alleviate the issue, the VZW rep may be right in that it is at the account level.
Good luck!
I am on T-mobile 5GB/month prepaid plan and would like to know if any of you have the same issue. What I found out is that download speed using ookla's speedtest app will show at around 10 to 25 mbps but I never got upload speed to ant stable level and average around 2 mbps regardless of cell tower, reception, or time of the day! It also seems that upload speed starts at 10mbps and after 1 -2 seconds will just stop, and then do like 1 mbps. Sometimes, ookla speedtest will not be able to finish the test using LTE and report network problems. I tried using different bandwidth test apps with similar results. HSPA+ does as usual, around 10mbps down 3 to 4 mbps up, no interruptions. Something is not working right and I sure don't like it. Yesterday, while connected on LTE my music streaming got interrupted and buffered every 20 minutes or so, like I am on EDGE, LOL (no actually... it's not funny at all). Hangout video chat (while on LTE) interrupted few times as well.
Update: Switching SIM cards didn't help. Upload speed is still extremely slow or will show network error. There are at least 6 other members reporting this issue with T-mobile LTE.
T-Mobile LTE here in Houston, TX. I'm don't have any issues that you mentioned above. Had the phone for 2 days.

you get throttled on prepaid to make way for the postpaid plans. its like this on every carrier.
Is this a new device / activation with a new(er) T-Mo micro-Sim card?
What device were you using before the N5? Try powering down the N5 and restarting it?
Reminds me of the old cable broadband days - turbo speed for that initial burst of extra speed, then it's back to same old, same old. Perhaps a lot of N5 on the special plan getting activated & seizing LTE's bandwidth ??
But, even HSPA+ speed is better than our soon-to-be history VZW 3G data with its lousy coverage at our home.

I used Galaxy Nexus and cut SIM card to micro size. Do you think it may make a difference if I replace it with new T-Mobile micro card? Why? What could be different? I would assume something like that may be the problem if I couldn't connect to LTE band- but N5 does connect with this (old customized) SIM when signal is available. I at first thought it was overloaded T-Mobile tower, but then I drove around and tested with the same results.

I had a 3 years old PAYG T-Mo Sim card ("regular/standard sized) and it was getting worn out from being swapped around - just by looking at the metal contacts) so I grabbed extra ones for 99cents (or was it free, whatever last month) just in case - not feeling to make a run to a local T-Mo store to ask for one to be swapped out. T-Mo support site mentioned about Sim card exhausion after 2 years (that's a new one to me too, but whatever) & that a new one should be exchanged - I couldn't swap it out online by updating or changing the Sim card, so ended up calling 877-xxx-xxxx & got transferred to a live operator and was done in less than 10 minutes, no questions asked once I came up with the correct PIN (ended up changing it anyway) - CSR didn't even ask for device's IMEI #, just read those long digits to him.
Waited a few minutes, rebooted and received 2 SMS & made a quick test call confirming that everything seemed to be working. It's working for me as I only switched to the $3 per day plan to check out the speed & back on PAGO by the minutes plan now on this line - it's my emergency backup line for voice calls.
I thought about & was ready to cut down the Sim to micr-Sim size with a template, but realized that by matching it to other free micro-Sims that I might be damaging the contacts as they are oversized beyond the micro-sim's dimensions.
If you have a spare free unactivated T-mo sim around, call them to swap it out to see if it might be the root cause - supposingly, older Sims like yours (and mine) might not be properly "provisioned" for 4G/LTE and possibly max'd out at 3G/HSPA+ in those days in their system's profile.
My friendly UPS driver just dropped off another free/free micro-sim plus a data only micro-sim for the tablet, so I'm going to play with the tablet and see how lucky I can get with the "free" 200MB monthly data offer.

Thanks. I'll get to T-Mobile store.
What does T-mobile say
There are at least 6 XDA members so far reporting issue with LTE upload speed on T-mobile. Switching SIM card to new one did not resolve the problem. One question for all with upload issues: Do you have 16 or 32GB version? I think it's vise to call T-mobile at this time in search for solution.

I have this same problem. Nexus 5 here, and upload tests are abysmal, usually ranking at about .5mbps, whereas download is 12+.
Using a legit T-Mo micro-SIM. HSPA+ does NOT have these issues at all.
At some point soon, I'm going to go down to the T-Mobile store, and hopefully run a side-by-side test between their T-Mo branded Galaxy S4 and other devices, to compare with mine. If theirs doesn't show this issue, I'm filing a support ticket, as well as contacting Google.
I'm on the same plan and hadn't tested until you posted this. For me the results did matter what server I was on. I got close to the same download speeds you posted somewhere between 25-30 mbps down and upload went from .5 up to 20mbps when I switched servers. I have definitely noticed this phone faster but my old galaxy never slowed down in the middle of a dl. Like you mentioned after a period of time on a download it gets throttled maybe upload to IDK (havnt experienced it yet) but for me on a big(er) app like dead trigger 2 or HD wigets I get a fast dl to about 30-50% of the app with it saying something like 3 min left, then once it hits the throttle point to something like 30 min for the remainder of the dl. forcing me to cancel or use wifi. So T-mo is def. capping or watching ea dl on an individual basis and deciding off ea request a certain (what they feel to be) acceptable size for that ping, most likely to try to get rid of leach tethering. not really why it effects the LTE more than hspa +42 data tho??
I recently bought a new, unused, stock LG G2 to replace a gray market unlocked BLU Products phone because after years of being with T-Mobile with various phones, then sliding on over to Family Mobile (Walmarts discounted subsidiary T-Mobile service), my signal dropped consistently - mainly at home. My service was fine for years before and for about the first year I switched to Family Mobile from T-Mobile, but then, I developed very poor signal at home within the past 6 months.
I thought there was something wrong with the BLU phone, so I bought the G2 about a month ago. Same problem, no difference. At home, signal was going from 0 bars to 2 bars maximum every 10 seconds making phone calls impossible. I need the phone for business so you can imagine this problem is extra bad for me. When I'm out running around, my signal does reach maximum bars at times. This was the same case with the previous phone. This usually happens without rhyme or reason, but within a 1/2 mile radius from home, it's still very poor signal. After being with T-Mobile for years, it's mighty weird that this developed recently.
I've called customer service about 9 times within 2 months. It was no help. They checked service/towers/coverage and everything is fine and well covered in my area apparently. I've been all over the web looking for answers, especially regarding a winning APN. I've used Family Mobile recommended APN settings, T-Mobile's recommended APN settings, I even used a combination of the two with Family Mobile APN with T-Mobiles MMSC. and vica versa. I also bought a new Family Mobile SIM card. So far, that's helped the most. I now usuallly drop down to one bar, no less, and stay there while at home but it's still not good enough. I also get 4G LTE now since installing and activating the new SIM, but data isn't steady either, and pages load slowly routinely.
As I understand, the At&t G2 uses the same and more bands than T-Mobile, so tower reception should be fine. Do any of you have an idea of what direction to go next? Is it a problem that this is a AT&T branded phone that I'm trying to put on the the Family Mobile network? An unknown to me tweak to the APN?
9 months ago I switched providers from NTT docomo (where I still used a SIM lock free iPhone) to SoftBank (where I got a new Pixel 3, and first time in many years that I got a phone + SIM).
But like how the whole nature of planned obsolence works, gradually going from best phone ever to falling apart to boiling my blood.
First the USB-C port of my phone stopped working (so I am now forced to use wireless charging and SFTP on a local network), then the FeliCa chip started becoming instable (which is fine, I can still switch back to a dedicated SUICA card where the FeliCa chip works for a decade), then I was forced to set up a finger print to use Google services (later on turned out to be just a policy issue in Google Apps, I already fixed that) which only makes my phone more insecure (random unlocking if accidentally unlocking the phone within 5 seconds or when the scanner touches the skin of my lag through my pants), but after I turned off finger print authentication my phone started to randomly unlock itself whenever I get extreme weather warnings (and since it's summer, I'm getting multiple times every day).
So I was looking for switching to another phone, and I bought a SoftBank branded Digno flip phone from Amazon, and my SIM card didn't work.
I went to SoftBank have them take a look, the guy was searching using my IMEI for 30 minutes only to tell me that the Digno problem is a very rare case and that Aquos flip phone doesn't have this problem because Digno is too old (released before 2015).
So I bought the Aquos flip phone that he recommended me, but again my SIM card didn't work.
I started to question it, and put my SIM card into my SIM free iPhone: didn't work.
Then I put it in an Aquos smartphone which I bought specifically as a SIM free phone: didn't work.
I went to SoftBank again (this time to a different store because I didn't have much time) and explained the situation.
The guy then told me that I must have my phone registered at SoftBank for the SIM to work.
Then I asked how I can do that, he said that I must purchase a phone via SoftBank instead of Amazon, or otherwise let a totally different SIM card get issued.
By this I'm not complaining or asking to hack the system, I only want to ask if anyone knows about such a tactic? Did anyone experience it too (in Japan or overseas)? And is it normal for a phone provider to lock your SIM card to a specific phone?
And while we're at it: if I flash my phone with a custom ROM, will this render my phone to be unusable with this SIM card as well?
Looks like you are down with a string of strange events and bad luck.
Softbank seems to be a d*ck and I would change a provider if I am you. It is illegal in my country, malaysia, to lock devices to network. But you can easily just register your phone imei to Softbank if you really like the coverage they provide.
As for phones I can't comment on that as I never used pixel, aquos or any of the phones you mentioned but the fingerprint able to unlock by touching your legs through your pants sounds like a hardware failure and I would bring the phone in for repair.

In my experience Docomo works really well within the Yamanote area of Tokyo, but I cannot afford living there and my work is just outside of that area.
And I already had home internet from SoftBank, which were the 2 reasons why I went with SoftBank, plus its coverage works really well (even when I go to a mountain village north from Sapporo, which I did yesterday, I still have really good coverage).
Their SIM only plans were also really good, I really feel like an idiot that I took a SIM + phone set this time…
My friends (I have them despite my username) also recommended me to go with au, but I didn't like what they covered (can't remember what exactly, but I remember it was somewhere among those lines).
But would be nice if our politicians would make this illegal too, once big companies obtain too much power, it's never going to be enough for them.
Edit:
I only want to add that the only time I had a bad coverage with SoftBank was when watching fireworks at the Edo river, but I'm not sure whether it's because I was near a big river or because the part of the river has a 3 point prefectural border (between Tokyo, Chiba, and Saitama).

It isn't a matter of "locking the device to the SIM", it is a matter of the device being registered on the service providers network using the device's IMEI number and the SIM card number being registered as being used with that device, both of these numbers must be registered together in your service account, that is how the network recognizes your device and how it knows to send service via that SIM to your device. When you switch to another device, the new device must be registered on the network and the SIM must be registered as being used with that device.
It's similar to registering your car and registering a license plate on that car. The car is registered to identify it as your car and the license plate is registered to identify that the license plate is for your car and not someone else's.

If it's true, then I'll try it out.
Somehow confusing if employees of the same ISP working at different branch stores tell me totally different things. (´；ω；｀)
