Do you know Sprint iPhone 4s is 4G


Recommended Posts

Last May I decided to travel to London so I called sprint to Unlock my iPhone 4S (international) they didn't mind. So I bought Vodafone sim card from London and I start using it over there (3G) only.

 

When I went back to the states I left Vodafone in my phone honestly I didn't find anything to take the sim card out so I can use sprint. so I took a bus from Chicago to Milwaukee then I noticed my iPhone roaming with ATT with (4G) and I did download test it was between 4-5 mg.

 

So the GSM part of Sprint iPhone support 4G for sure, So I decided to try it again, I bought GEVEY Ultra S to unlock it, you need to jailbreak it so you can unlock it,

 

It works great with AT&T 4G speed!

It works with hspa+ I believe, which is att and tmobile 4g. Although att is switching to lte now as their official 4g.

The iPhone doesn't support AWS bands(which TMO's 3G/4G is build on), but some areas are becoming compatible with the iPhone since they started deploying 3G/4G on iPhone-supported bands.

Nope. By no universally accepted standard is any iPhone "4G." The iPhone 4S supports W-CDMA Release 5, Category 10 -- HSPA 14. That is not even HSPA+ 21 or 42, which some call "4G" but I do not. "4G" is fourth generation, and that means an OFDM airlink plus a full IP core. Data speed capability is not the measure of the generation of a wireless network.

 

For a parallel, you can bolt a jet engine onto a Ford Pinto and make it nearly as fast as a jet. But that does not make a Pinto a jet.

I'd never heard those specific definitions attributed to 4G before either, I don't think anything in IMT-Advanced requires OFDM and even the connection between IMT-Advanced and the term "4G" is a bit tenuous.

Apple released a software upgrade that literally just turned a 3G icon into a 4G icon so people could say "wow my phone has 4G on AT&T".

 

Nothing actually changed except the little icon. As WiWavelength has just explained, it's not "4G".

 

The biggest issue with AT&T's HPSA network is that the speeds are extremely variable depending on how loaded an area is.

Apple did this because AT&T leaned on them to do so...and it's annoying that I have to explain to people that the iPhone 4S cannot do actual 4G, no matter what that icon says. As WiWavelength said, the fastest the phone can do is HSPA 14.4 (not H+), which will get you some good download and upload speeds, sure, but 'tain't 4G.

 

What's funny is that a good friend of mine has a 4S here in Fredericksburg, which AT&T shows on their coverage map as 3G (I think due to lack of backhaul; I believe the air interface is H+ but it doesn't matter much because speeds top out at a couple Mbps). He gets the 4G icon on is 4S. If I had an iPad running on AT&T, I wouldn't get the 4G icon on the exact same network...but hey, AT&T is compensating...for a small LTE network :P

If it can do 14.4 mbps then that means it's doing 15/16 codes which means it falls under the HSPA+ revision of the specification. Realistically the only difference between that and the 21 mbps speeds are the use of 64QAM and more aggressive error correction, which is only going to be a factor typically at 1/3 cell radius or less.

 

Remember that what people had been calling "real" 4G up until about 18 months ago needed 128QAM in 60+ MHz and nearly no error correction. Nothing currently deploying is even half way to the older more strict usage of the term.

    • Looks like there's a slightly taller building going up next door to where the decommissioned site used to be. Taking a look at StreetView, T-Mobile likely decommissioned the site because the east facing sector would blocked by the new building. If I had to guess, T-Mobile has already agreed to move to the roof of the new building and is just waiting for it to be completed to install the site there. What they should've done is just rearrange the sectors in the meantime but it seems like T-Mobile just bit the bullet and decommed the tower in the short term. — — — — — A permit was issued for a Sprint conversion at 150 Prospect Park West, finally filling in what is T-Mobile's largest coverage gap in Park Slope. Verizon is collocated on that building and AT&T has placed small cells along Prospect Park West to fill in coverage there while T-Mobile struggled using two sites, one at Grand Army Plaza at the far north and another at Bartel Pritchard Square to the far south.  
    • Yep, you can see the site was taken down between Aug 2022 and Apr 2023.
    • Verizon site at Woodbury Commons finally got C-band. I'm seeing upwards of 600Mbps there, a massive improvement over the <1Mbps I used to see. LTE is now at 10-20Mbps which is significantly better than before where speed tests would often fail. My only complaint is that C-band is super inconsistent. Not sure if it's a software issue but sometimes I'm connected to it and get the 600Mbps speeds previously mentioned and other times I connect and only see 15Mbps. Seems like whatever load balancing the network is trying to do is still shoving a ton of people to LTE, even in conditions where I have a strong C-band signal.  — — — — — You're absolutely right. The site on top of Bais Sarah Hall at 6101 16th Ave got decommissioned. Sad that they haven't installed a new site to fill in that coverage gap.  — — — — — In other news a carrier reached out to the board of my grandmother's building in Brooklyn about installing antennas on top of it so she called me today because she knows I map cell towers and she said a lot of people in her building, especially the folks on the upper floors, are worried about the health effects lol. I asked her if she knew what carrier it would be but she said she doesn't know. A quick glance at Cellmapper tells me it's either Dish or AT&T since Verizon and T-Mobile both have sites within a two block radius of her building but AT&T barely builds new sites so I'm leaning Dish. They're asking for a 25-year lease with an option to renegotiate the lease after 10-years. The board of her co-op said that if they do it, maintenance fees will go down since they'll be offset by the rent that the carrier would be paying them. She said she already voted in favor of it but she thinks that a lot of the older people in her building are against it.
    • Galaxy S7 FE most certainly doesn't have the same level of NR CA (if at all), it also looks like it doesn't have SA NR, so it's is inherently going to be much slower since most of the spectrum is now focused on NR rather than LTE. It's likely the same generation radio as the S21 (or maybe S20). Having trouble finding which it would be.
    • T-Mobile seems to be paying close attention to how much of B2 they refarm for NR, as on this trip down to South Padre Island I saw both 20x20 n25 and 20x20 B2 (but not both simultaneously) at various points on the trip. At South Padre itself, seems like someone else has 2.5 GHz licensed so the n41 setup here is 20+80 MHz. Speeds are still decent, but VZW has 100+60 MHz n77 live (and AT&T has some 80+40).
