"4G" (or Faux G as I am fond of calling it) is the biggest bunch of marketing bull crap I've seen in a while, purposely worded to confuse customers.
To keep it brief and simple (which it actually is, truth be told) "4G" (including LTE) refers to a couple of concepts: 1) Data download speed capacity of the phone and 2) the specific bands the phone supports.
Generally, a phone with a download speed >= 21Mbps download speed (HSPDA) is classified as "4G" (which as another poster noted can show up as 3.5G or H+). However, whether that phone will get those speeds on YOUR network depends on the bands involved and how congested that network is. For example, the BLU Studio 5.5 D10A supports 850/1900 with HSDPA, 21 Mbps; HSUPA, 11 Mbps. That phone would probably show "H+" as the connection speed (effectively 4G). HOWEVER, unless you are on a thoroughly refarmed T-Mobile network, that could easily drop to 3G or 2G because, again, the 1900 band is the only compatible band that this phone has.
So, just because a phone technically has 4G capacity does not mean you will automatically get those speeds in reality.
Anonymous, 09 Feb 2014This phone that you have, can use only 2g or 3g speed and no 4g speed. Go to google and look u... moreActually the phone does get 4G. It Gests HSPA+ Which Is 3.5G And T-Mobile & AT&T Consider it as 4G.
This phone that you have, can use only 2g or 3g speed and no 4g speed. Go to google and look up "blu cell phones" and you will be taken to to the manufacturer of your cell phone. Then look up your model number and then specifications and you will find that the phone uses 2g or 3g speed only. If you use 2g then your battery lasts longer and on 3g, it(battery) lasts less. Be safe P. Long

gaeth, 07 Feb 2014i cant conected with 3g netwoek its show me 2g network when i search for networkWho is your service provider? The BLU Studio 5.5 D10A has bands that are made for AT&T 4G/3G (assuming you are in the United States). Please check your provider's cell phone bands for cell data and make sure those are compatible with the phone you've purchased. Also make sure your phone's network settings are correct.
Anonymous, 04 Feb 2014All Blu phones are 3g only with the exception of the Blu Life PureThe blue 5.5 Is 4g I own three of them. Just make sure you get the" A version" and not the" I version". I made that mistake on my first purchase.
i cant conected with 3g netwoek its show me 2g network when i search for network
Can anyone help me. I can't find 3g network on my phone its find only 2g network
I see a lot of you have issues, now going in.....Most of the blu devices have HSPA+ in them aka 3G+ or 4G but most wont get it due to the wrong bands....tmobile has HSPA+ in 1900 but only in the same areas that they have 1700 LTE...they did both upgrades at the same time 1700 LTE and 1900 HSPA+....so if you have a studio 5.5 which is 850/1900 or 850/2100 you will only get 4G speeds while in an overlayed 1900 HSPA+ area...besides that EDGE...Blu is working to make more devices that work with 1700 HSPA+......I love blu phones....any questions facebook us at U.P.Wireless LLC...13 years+ experiences with GSM phones and all networks
I've owned this device for about 3 months and I love it! Right now the OS is sick on 4.2.1 with no Kitkat upgrade on the horizon unless you root it and install a custom rom (I highly recommend doing this).
Now, if you're looking for 4G speeds, you might want to look at another Blu device, preferably the "Life" Line, you might achieve 4G speeds. The box does boasts 4G speeds; but you're only getting HSPA or HSUP; Edge/2G will be the norm for this puppy and yes days download are equivalent to dial-up.
Before you actually purchase this device, make sure the frequency matches up to T-Mobile or AT&T or any other GSM networks. Last thing you want to do is look stupid with an StraightTalk/T-Mobile sim in your hand and your device is wired to the AT&T network.
Can somebody tell please if there is a difference in quality of communication, connectivity, etc. between Att&T and T Mobile. Thanks a lot.
