Post your speed USA EDGE

Is anyone using the A8181 on USA EDGE network. Would it be possible to post your download and upload speeds? I have one coming in the mail and I haven't decided what to do with it.
I am thinking of selling it to get a Nexus One, which I sold to get a Slide.
is 900kbs/sec out of the question for edge? 1mb?

Yes, 900 kb/sec is out of the question for edge.
EDGE (Enhanced Data rates for GSM Evolution) or EGPRS provides data transfer rates significantly faster than GPRS or HSCSD. EDGE increases the speed of each timeslot to 48 kbps and allows the use of up to 8 timeslots, giving a maximum data transfer rate of 384 kbps.

Remember, that is max possible speed. The real-life speed is much lower.

Thank you. I don't think I can live with 328 max. My slide is getting 3000+, on the new updates. That is in the peak in city though, in my neighborhood I average 1200 or so. Looks like I will never get to know the Desire.

You didn't understand what I quoted. That is the max speed of EDGE technology, it has nothing to do with Desire, Slide, or whatever. That is the technology capacity.
Are you sure Slide is on EDGE and not on 3G or HSDPA?

My mistake, I understood. I forgot to tell you my service provider, sorry. I have a USA t-mobile and I pay for 3G service.
If I use the A8181 in the USA it will only get EDGE, SO FOR ME**key words** it will not go faster than the EDGE technology will allow it.
On my slide I am able to pick up USA 3g and hsdpa+ as you can tell from the speeds I listed
My low end speeds are around 700 and that would have been enough hypothetically. But I am an idiot, because I should just disable my 3G and run an edge test from my own neighborhood.
Thank you again though, you gave me EXACTLY the answer i was looking for, and quickly.

I wish man. The A8183 will work on USA ATT 3G. I am stuck with T-mobile.
If I had ATT I would look into the A8183 for sure.

I have a A8183 that I bought in London and use it here in the US on AT&T...no 3G only EDGE.
3G bands on this phone are limited to 900/2100, AT&T uses 850 and 1900.

A8183 is the Aussie model, not the Euro model, which is A8181.
A8183 = 850/1900mhz 3G
A8181 = 900/2100mhz 3G

Actually if you look online the A8183 uses 850/2100 bands for the Data.

Oops, you are correct.

A8183 on US 3G
Is AT&T the only US 3G network that the A8183 will work on ?
I ask because I am trying to find a phone (ideally a Desire) that will work on UK 3G and US 3G.
The A8183 does 850/2100 which I believe will let me do this ?
thanks

Alternatively, you could get a Nexus One as this will work on TMo in the US, and on UK networks.

can I port GT-I9250 to Softbank (Japan) and use Ultra Speed?

I'm staying in Japan for couple of months, and I'm planning to import GT-I9250, so that I don't have to keep paying for data rental service, but I'm now wondering whether I'm stuck using docomo, or I could go to softbank.
Since the phone doesn't support LTE, I would rather go to softbank and use their ultra speed. Can any body let me know whether this phone works with Softbank, and ultra speed?
I know it should be as easy as checking frequency. However, GT-I9250 does not officially support Japanese frequency, but I have seen reports that proves otherwise.
I would appreciate any help!

[Q] Lenovo Z90-7 (VIBE SHOT) 4G UK HELP PLEASE?

Hi guys,
I have just bought this phone and flashed it with the latest firmware Android 5.1 as per the post on this forum. I am now very worried because my phone only seems to be connectiong to 2.4ghz network instead of 5ghz. Also I cannot get mobile data working.

What ROM/kernel did you flash? Many ROMs run 5.1.x

Hi I used this rom Z90a40_USR_S118_1505272046_Q2020131.4_ROW_qpst
which was mentioned here on the forum as the best for Android 5.1

Hey man, I've done some research and it seems your ROM/phone should support LGT(4G). I would highly suggest completely wiping your phone, reflash ROM/ Gasps/ kernel (if you have one) and see if the issue persists

The seller says I can send the item back for a full refund but unsure if he will give me a refund as I've changed the ROM to 5.1 The worst thing would be sending the device back to China

Okay, have you tried manually setting your APN? Fallow the steps below and findnthe APN settings online for your carrier, let me know what happens.
Many users have told me their 3G/4G LTE data network connection is broke after installing a custom ROM. *Well, in most of these cases, it can easily be fixed by manually setting the APN (Access Point Name). *This applies to any GSM networks such as*AT&T or T-Mobile. *For CDMA networks like Sprint or Verizon, they also use APNs but you don’t have to set them and should work out of the box.
Every carrier uses its own APN Settings to get its 3G/4G LTE network working on an Android smartphone or tablet device. *Now, these APN settings are usually “downloaded” automatically to your*phone*when you insert a SIM card. *BUT, there are times where the APN are not selected automatically OR when the APN settings are not downloaded.
In those instances, your 3G/4G LTE data will not work but that can easily be fixed.
Step 1. First, browse your Settings menu and find the “Access Point Names” menu. *This is usually under “Mobile Network Settings” or “More*mobile Networks or “Mobile Networks” under Settings menu depending on the Android device used.
Step 2. Once you are in the APN Settings menu, first thing you should check it that the APN is on the correct one. *If the correct APN is not checked (sometimes this happens), simply check ON the correct APN for your carrier. *That will make your 3G/4G LTE data working right away
tep 3. There are also times where the wrong APN is listed or there’s simply no APNs listed. *In these rare cases, you can simply add a new APN, hit the “+” button.
Step 4. For APN setting, the “Name” can be anything. *“APN” setting is the most important, usually you only have to fill this out for your phone to work.
For T-Mobile, you can set the “APN” to “fast.t-mobile.com”. *AT&T, you can set “APN” to “phone” or “pta”.
Now setting “APN” will get your data working but you still need to input additional settings to get your MMS working.
ep 5. You can usually Google APN settings for your carrier. *Whether you are in Thailand or in the U.S., simply Google for your APN settings like:
Google “t-mobile APN 4G LTE” for T-Mobile 4G LTE APN settings in the U.S.
Google “True Move APN 3g” for True Move 4G APN settings in Thailand.
Eventually, you should be able to find the full APN settings for your carrier whether you live in Hawaii or on North Pole.
Once you have the correct APN settings, simply input them into your APN settings on the phone
Step 7. Next, make sure to select the new APN Setting you have saved. *Within 5-30 seconds, your phone should start picking up 3G or 4G LTE signals and your data should be working again on the phone.

Hi guys,
I have just bought this phone and flashed it with the latest firmware Android 5.1 as per the post on this forum. I am now very worried because my phone only seems to be working on 3G. When I go into settings and network it only gives me the options to pick a 3G network. I did a lot of research before buying this phone and was assured it would work on 4G within the UK my old phone the Sony Xperia ZR worked on 4G fine. I do have the latest nano sim.
Here are the details of the Lenovo Z90-7 As per GSM Arena
Technology
GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE 800 / 1800 / 2100 / 2600 - Lenovo Z90-7
And from my network operator's webpage I get the following info
4G from Tesco Mobile (o2) uses the following network frequencies:
800 MHz (0.8 GHz)
Am I having this problem as I flashed it with new firmware?
Click to expand...
Click to collapse
I believe the phone doesn`t have the LTE 800 frequency.
Search other websites than gsm arena.
That`s why you don`t get 4G.

Hi Friends,
Thanks for the quick replies I really appreciate the help. In regards to the APN settings I've checked these and these seem to be correct.
So it *Should* work EE

Interesting, I was hoping the APN settings were the cause. I'm sorry you couldn't fix your issue. I'm sure you will have better luck with your next device.

Valter84 you are correct I spoke to the seller and he advised that there is a mistake on the listing the phone does not support the LTE 800Mhz frequency.
So it *Should* work in the UK on the network EE which uses Band 3 FDD LTE (1800mhz). I've tried an EE sim and it still does not work at all on 4G.

Hi, I have the same trouble as you , anyway I have not flashed my Z90-7 yet. My chinesse seller from Aliexpress claims , that this phone supports all usual LTE frequencies including 800 Mhz.
But I can use here in Czech republic at T mobile provider only 1800 Mhz which covers only Prague and Mlada Boleslav . Rest of our country covers LTE on 800 Mhz only.

This seems to be a worldwide problem outside China. It is nothing to do with APN settings, etc.
A company is selling this phone on Amazon USA and they have specifically mentioned 4G does not work in the USA.
I am based in the UK and 4G doesn't work. I have flashed the phone and have now android 5.1 installed on it, but until official EU version of this phone is released we will be stuck with 3G

So, my phone's android version is 5.1
Z90-7 device can't support 5ghz WIFI network? or ROM's problem?

Dear people, wake up, many Chinese markets are deceiving customers by providing them misleading information. LTE bands is one clear example. Chinese LTE bands are diferent and they just flash the device's ROM for multi-language and add Google Play to make it "international version" but it is not. DON'T BUY IT!
I double checked with this company minideal.net which i cannot recommend. The company confirmed full FDD LTE (4G) functionality on following frequency bands: 800/1800/2100/2600MHz. But my smartphone IS NOT WORKING on 800MHz in The Czech Republic because it is only 1800/2100/2600MHz in fact. Within the PayPal Dispute and Claim they completely turned around their statements concerning LTE bands.
Complete tests were made with my network operator provider to rull out other problems. You can easily check that in these comments and in some fair e-shops where they don't twist the truth.

This is correct, the phone doesn't work on 800MHz. However it should because Qualcom 615 supports 800MHz. the reason it doesn't work is because the modem is probably locked within the ROM. I am hoping once this phone is release european version then it should work at 800MHz.

Hi, i already have had the European version of Lenovo Vibe Shot (chinese name Lenovo Z90-7) in my hands. I purchased it recently to compare the Czech and the Chinese model concurrently. All worked perfectly well with the Czech model. The device connected to 800MHz LTE band (band 20) INSTANTLY after the Android system start. No setting necessary at all. It connected to 800MHz T-mobile band in the Czech Republic. While with the Chinese only 3G or less! Another LTE band (2100MHz perhaps) worked well - Vodafone Czech Republic. So LTE hardware is ok but 800MHz missing...
The test is here: youtube.com/watch?v=Mv5RoN_BYSc
No doubt i was intentionally deceived by the seller namely minideal.net; and many others customers are being deceived the same way!

Well, i consulted this with some mobile phone services earlier and they did not recommend updating the ROM like that. Your device can end up dead after it. The ROM must be perfectly tuned to the particular HW specification of your device to avoid the fatal consequences. It is quite risky... i was thinking the same way. I am disputing the seller via PayPal asking for partial refund to be able to re-sell the phone to someone who can do without 800MHz.
Also you cannot freely update the android system without loosing the multi-language and Google Play... So shopping mobile phones in China? NOT A GOOD EXPERIENCE FOR ME!

Ok, i understand your point. I was thinking the same way. Some mobile phone services would refuse to update the ROM like that though, because it can kill the mobile completely. And who will take the responsibility? The Chinese dishonest dealers should! Let us tell them, we don't like their deception and lies! They are playing the "we don't know" game, but they surely know enough about the differences between Chinese and non-Chinese LTE bands.
But yes, there should be a way to change the ROM the same way the distributors of the real European version of this phone do it. Only where shall we get that ROM and ROM update done? Because, as i have already experienced, the local (Czech) Lenovo representation has no interest in helping owners of Lenovo products purchased in China. How predicable...

ZUK z2 lte works only in big city

Hi everybody! I bought this phone and works nice except lte. LTE is available only in big city not in my town In compare with my old LG g3 that has lte signal in my town... I think it is because of chinese lte bands, right? Is there any chance to solve it? I'm from europe. Thanks for any idea!

I bet your operator uses LTE 800Mhz outside cities and Z2 doesn't have that frequency. No way around this. Use 3G instead outside of cities.

Dear friend
If you reside in a particular location and the nearby tower is having many bands of same operator. Our mobile phone latches to a particular band or a combination of band called carrier Aggregation or LTEA depending on the configuration of cell site. You can try any combination which gives best speeds at your place and also coverage.
