Sprint SIM card -> T-Mobile SIM card experiences?

Post by djm2001 »

T-Mobile has been pushing me to switch from my old Sprint SIM card to a new T-Mobile SIM card, and I just got an email saying that I need to do this by Jan 1, 2022 because they will retire the Sprint CDMA network.

For those who have already done the switch, has your post-switch coverage/quality been an improvement or a step back? (I found a Reddit thread where people were complaining about their service after the switch, but the thread title was framed negatively and so perhaps there was some selection bias in the replies.)

I switched over about a week ago. I haven’t noticed much difference at all. I’m in a metro area, so all carriers have relatively good service though.

Do you have an older phone? I have only gotten emails inviting me to switch, but nothing saying I have to switch.

No problems for me. I went to a Sprint location, and they switched it for me.

They sent me a SIM card to switch. I switched, but I couldn't get service. Called and they said I needed to upgrade my phone to work on their network. Asked why they sent me a SDIM card to put in this phone, they didn't have an answer they just reiterated I needed to upgrade now and swap that SIM into the new phone.

I ended up swapping back to my SIM from Sprint for the time being which required a couple auth steps, opposed to switching the Sprint for TMo. This happened the afternoon of their hack. Didn't shed a good light for them for me. Doubly annoyed as I have the Cat s48c and they won't just replace the Sprint model for the TMo model.

My siblings have switched their SIMs. Mixed reviews of signal quality. One in AZ says it seems every time the internet goes down, his phone service is poor.

I switched a few months ago. No issues, except that T-Mobile spams my phone way more than Sprint did.

Also, I had a Samsung Galaxy S7, which is why I had to switch. Upgraded to Samsung Galaxy S21+.

Interesting. T-Mobile warns me about potential spam calls. Sprint never did this for me.

I got spam call warnings from Sprint. With T-Mobile, I get notifications about their apps, about uninstalling apps to save space, and then asking me to install their apps instead, and on and on.

No issues. Coverage/speed will vary depending on your location. Mine did not improve any.

Did the switch. Much better coverage. The switch had some hiccups, mainly due to me not remembering my sprint or t-mobile ID, which was made worse by me switching from t-mobile to sprint.

Definetly do it. Lack of phones in stock was a reason I didn't do it before. I didn't want the free phone but was willing to pay $300 for a midrange one

If you have a store nearby have them do it.

I did it on one of our phones, and coverage got WORSE in some of the more remote areas we spend time in.

OP,

T-mobile gives me and my wife a new Samsung A32 to switch. Need to use chat support to switch. Other than that, no problem. I have to turn off WiFi calling to make my phone call and SMS reliable. It is on by default.

Do you try to use the WiFi calling on your phone? Was it on or off? It is one of the setting on your phone app.

They offered it. The phone were free as long as I stay on the same plan for 24 months. If not, I pay the prorated amount by remaining months.

I believed that they mailed me a letter. I cannot be sure. I know that this is happening so I called them.

I switched the SIM card two months ago. Haven't noticed any issues with coverage. The rep at the T-Mobile store told me the company is taking down Sprint towers and eventually the coverage with Sprint SIM is expected to get spotty.

t-mobile coverage has gotten dramatically better the last few years as they've added long range band 12 and band 71. it's worth getting a new phone that supports both of these if you ever go places with iffy coverage

look for a new phone on this page

Made the upgrade. Seemed ok.

Went overseas. No connection despite global roaming being in my plan and being in a covered area.

Customer service would not help. They said I needed the security pin. Had it at home. Couldn't log in to my account to view it (it's online) as I needed 2FA verification via text message to access my account and view it. Was overseas without a connection and they couldn't not do 2FA any other way. No, being on wifi doesn't get the 2FA. They said bring it into a store then ... All customer service would do is upsell me on unlimited calling overseas which would "solve" my problem. I said data roaming/calling is already included and I don't need it that much. I repeatedly had to point them to their own documentation for them to finally acknowledge that was the case. Sigh.

Am using Google FI now after explaining this what seemed like six times to finally get T-Mobile to unlock my phone and port the number.

Not really sure if network failure overseas is related to the upgrade or not. Just be sure to have your security pin on hand if you do travel and it fails. That's my advice.

After some problems with trying to transfer to T-Mobile SIM cards, I ended up switching to Google Fi as well. The SIM cards that T-Mobile sent me wouldn't activate. T-Mobile support told me that it's because my phone did not support 5G and that I need to upgrade them. Well, I'm not willing to buy new 5G-enabled phones just because T-Mobile wants to save money by shutting down Sprint's old network. I also don't want to take their offer for discounted phone upgrades because I don't want to be locked into their plan for another 2 years.

Google Fi is working well so far -- I drove from DC to FL this week and got good coverage the whole way down except for some rural areas in north central FL. The activation and transfer process has been painless so far. Fi allows me to transfer my Sprint family plan lines over one by one (useful for testing a couple of lines before moving everyone over), and allows me to keep my existing phones and phone numbers. I have 6 phones on my Sprint family plan, and have successfully switched over 2 of them -- a Pixel 4a and a Moto X4.

You could have just stayed with T-MYIobile and gotten new 5g phones for free over 2 years, if you cared. Just FYI. On an old grandfathered family plan, and we did it, got 6 free phones (could have gotten 8)

The original offer was Samsung a32 5g , which is really nice, got 4x. The current offer was Oneplus n200 5g , which is also nice (worse camera tho). You have to trade in ANY phone that powers on and is not physically cracked. We traded 4 year old phones with no problem.

I didn't take that offer because, as I mentioned, I didn't want to be locked into T-Mobile for 2 more years. They offered me a free device upgrade for only two of my six phones. For the rest, they offered subsidized (but not free) upgrades. I surmised that the free device upgrade applies only to older phones (iPhone 7, Moto x4), not newer ones (Pixel 4a, Moto G Power, iPhone 12, etc.).

After some problems with trying to transfer to T-Mobile SIM cards, I ended up switching to Google Fi as well. The SIM cards that T-Mobile sent me wouldn't activate. T-Mobile support told me that it's because my phone did not support 5G and that I need to upgrade them. Well, I'm not willing to buy new 5G-enabled phones just because T-Mobile wants to save money by shutting down Sprint's old network. I also don't want to take their offer for discounted phone upgrades because I don't want to be locked into their plan for another 2 years.

Google Fi is working well so far -- I drove from DC to FL this week and got good coverage the whole way down except for some rural areas in north central FL. The activation and transfer process has been painless so far. Fi allows me to transfer my Sprint family plan lines over one by one (useful for testing a couple of lines before moving everyone over), and allows me to keep my existing phones and phone numbers. I have 6 phones on my Sprint family plan, and have successfully switched over 2 of them -- a Pixel 4a and a Moto X4.
You could have just stayed with T-MYIobile and gotten new 5g phones for free over 2 years, if you cared. Just FYI. On an old grandfathered family plan, and we did it, got 6 free phones (could have gotten 8)
How do you do that? I am still on an old Sprint plan and keep getting asked to switch to a T-Mob sim but no mention of a free phone.

The original offer was Samsung a32 5g , which is really nice, got 4x. The current offer was Oneplus n200 5g , which is also nice (worse camera tho). You have to trade in ANY phone that powers on and is not physically cracked. We traded 4 year old phones with no problem.
I didn't take that offer because, as I mentioned, I didn't want to be locked into T-Mobile for 2 more years. They offered me a free device upgrade for only two of my six phones. For the rest, they offered subsidized (but not free) upgrades. I surmised that the free device upgrade applies only to older phones (iPhone 7, Moto x4), not newer ones (Pixel 4a, Moto G Power, iPhone 12, etc.).
Is Google Fi limited to Pixel and Moto phones?

Other phones are supported. You can check compatibility here.

Thanks! :sharebeer

I will have to look into this, Google Fi looks cheaper than anything I can get on Sprint/T-Mob.

T-mobile reception is none inside my building. at least Sprint gives me 3G. If they force me to change, I would cancel the cellular service .

For those who have already done the switch, has your post-switch coverage/quality been an improvement or a step back? (I found a Reddit thread where people were complaining about their service after the switch, but the thread title was framed negatively and so perhaps there was some selection bias in the replies.)
Do you have an older phone? I have only gotten emails inviting me to switch, but nothing saying I have to switch.
You have to switch any phone on the Sprint CDMA network, we will be shutting that down within a year as we need that bandwidth for the 5G rollout.
I'm a former Sprint employee now working for T-Mo.

The process is painless on your end as long as you have an approved T-Mo phone which is 98% matching with the Sprint phones. Funny enough my Pixel 4XL is not on the list as it's not supported on the T-Mo back end retail system. I will be upgrading to the 6 Pro when it comes out.

Just go to a T-Mo store and have them do it. You can also get a do it yourself card with a new Sim in it if you want.
The only gotcha is if your an iPhone user, you need to turn off the "locate my phone" feature before switching it out.

No problem with the change in a Samsung Galaxy S8

Free upgrade terms are limit 4 (per model, you can get 4 of each of the free models) and you can trade any working phone. I don't know what they "offered" you, but those are the terms in black and white for anyone to read

Since you are an "insider" do you know if once I switch to a T-Mo sim via the mailed kit, whether I can from there just put that sim into any T-Mo compatable unlocked phone and be good to go? With Sprint, you used to have to do some kind of funky activation process with them either online or over the phone every time you got a new phone.

Glad to hear Google Fi is working well for you.

To follow up, Google Fi is working great for us overseas as well. Twice Sprint/T-Mobile couldn't get their roaming to work and implied it was because we were using a discounted plan and should change which was absolute non-sense as roaming was stated to be included on the plan in the area we roamed. Google Fi had no trouble and cost less that the Sprint/T-Mobile plan that didn't work.

It's a relief to have overseas roaming actually work as promised.

I switched a few months ago, mainly because I wanted to use T-Mobile scam shield to block unwanted calls.

Works fine for me, no noticeable difference in call or data experience.

Yes, I am on a ridiculously cheap, unlimited everything plan for 2 phones.

Sadly no the sim is tied to the IMEI hardware number of the phone and will not work outside of that phone.

The Sprint plans will be going away an about a year when the CDMA network is turned off.
The Sprint/T-Mo plans are not comparable on the back end.

I don't want to be forced to change plans because of the sim swap. I just got the T-Mo sim in the mail.

Yes you ether go into a store or call the help line they will do the same thing.

The help line will try to activate an e-sim (verses a physical sim) first but I've found that to be 50/50 personally.
I just activated my new Pixel 6 Pro and needed a real sim the e-sim didn't work after three tries, lucky I had one.

I'd go into a store and at least ask for a sim card or just have them do it. I couldn't give up my old Pixel 4XL in
store as it was my only way to login to the company vpn so I did it at home via the retail help line.
