E70-1 reception on GSM 850 Network?

Hello, I am located in the US. I recently purchased an unlocked and new Nokia E70 from Amazon.com After I purchased the phone, I noticed that I had good reception at my office, but very poor or no reception at my house. This was strange because my Nokia 6800 has good reception both at the office and at home. I learned that my phone is the E70-1 (GSM 900/1800/1900) whereas my carrier operates on the GSM 850. My friend has the E70-2 (GSM 850/1800/1900) and he gets very good reception at my house! Question: Is this a hardware problem (antenna), or can it be fixed through settings and/or software? Can I download the North America software package into this phone and take care of this problem? Can Nokia replace the antenna if I pay for the service? In short, what can be done to convert this phone so that it works ideally on my Cingular network? Thanks, Art

While very similar in hardware terms there are enough differences in some RX path areas to make it impossible to convert from 900 to 850, sorry. Even if you could do the hardware changes the software changes required would need an expert in low level programming to implement. Sell it on ebay and get the correct model.

  • Nokia 5030 and GSM 850/1900

    Hi,
    My brother bought a Nokia 5030 phone for his trip to the USA, on the Nokia website at http://europe.nokia.com/find-products/devices/nokia-5030/specifications Nokia 5030 according to specifications it support the following frequencies: EGSM 900/1800
    GSM 850/1900 
    The phone worked fine on the EGSM 900/1800 Frequency. 
    Before buying we checked with Nokia support and they told him that the phone should work in the USA. Now he is there and his Nokia 5030 couldn't detect any operator either by auto or manual search, he tried putting his SIM card in another phone and it detected a network, so its not the SIM.
    I have tried contacting Nokia support in my country, and they still told me that the phone should work in the USA.
    They told to try and perform a factory reset, but it didn't help.
    Also the box says "made in Romania" and it has only EGSM 900/1800 written on it.
    Also in the manual there is in mention of GSM 850/1900 frequency.
    (http://nds1.nokia.com/phones/files/guides/Nokia_5030_UG_en.pdf)
    My brother had to buy another phone (a Nokia) to communicate with me.
    Is there something wrong with that particular Nokia 5030 phone,
    or it does not support GSM 850/1900 frequencies,
    in that case why Nokia support tells me that it should work and the Nokia website lists that frequency in the specifications.
    Thanks.

    Hi,
    I see I’m not the only one that encountered that issue.
    I think that unless you have a manual or box that says that the device supports GSM 850/1900 frequencies, it will unfortunately not work and I think that software update won’t solve it as it appears to be a hardware issue.
    Its looks like that they’ve listed this phone as a quadband in their internal documentation so that the tech support and sales thinks that this phone is a quadband while its not.
    (I called twice before buying and spoke with two different customer service representatives that assured me that the phone supports the US frequencies, and that it must have been a mistake that the manual does not list it as such.)
    I hope that Nokia will notice and finally update the Nokia 5030 online specifications page, so that it would explicitly state that Nokia 5030 is not a quadband phone, like they did with their other phones.
    Here is a little update:
    After escalating my support request, and speaking to the customer support manager (and repeatedly asking for them to verify it with global Nokia), Nokia Israel (It’s actually represented in Israel by a company called Eurocom) acknowledged my request to return the phone for a full refund to the retailer, and offered me a small compensation (which I guess is better that no compensation at all).
    Today I should return it to the retailer, and I hope there won’t be additional problems with that.
    One thing I liked about the phone, (I guess this feature is available on most new Nokia’s phones) is its alarm clock feature that pronounces the current time as it tells you to wake up…
    One more thing,
    Notice the fine print that appears on the nokia 5030 specs page:
    “The availability of particular products, services and features may vary by region. Please check with the Nokia dealer nearest you. These specifications are subject to change without notice”
    I hope that you will be able to solve the problem like I did.

  • What is it like, using an iPhone 5 on the att GSM Wirless Network?

    What is it like, using an Unlocked iPhone 5, on the AT&T GSM Wireless Network?
    Cost per Month ?
    Signal Strength ?

    AT&T posts their plan prices very prominantly on their web site.  You cannot use an iPhone with AT&T without a voice and a data plan.
    Personal, I really like AT&T's service with my iPhone 5 (as I did with my previous 3 generations of iPhone).  Their LTE data is superb in my area, and voice calls are great.  Like any carrier, their network quality and coverage will vary a fair bit around the country, so their is no single answer as to how it will work out where you are.  That is why you get a 14 day trial period on any new contract.

  • 1208 working in the GSM networks in the U.S.?

    Question: any idea whether the 1208 model would work in the U.S. GSM networks?
    On the sales package I got there is this marking
    "GSM 900/1800 EGSM850/1900" which I believe indicates that it should work in the GSM networks in the U.S.
    When I tried the online phone feature comparing tool on nokia.com, it's also indicated there that the frequency bands include 850/1900.
    But the user guide of my phone (9202384/Issue 3 EN) says
    "The wireless device described in this guide is approved for use on the GSM 900 and GSM 1800 networks."
    That is, the phone would not work on the 850/1900 bands.
    So which info is correct?
    Thanks

    Hi guys,
    I found your posts and got strongly interested in.
    I'm on a business trip in Canada. I bought Nokia 1208 in Russia, my service provider is also in Russia and gives me international roaming including a one in Canada.
    The operating frequencies mentioned on the phone wrapping are exactly the same as “pafr” wrote above. And the ones mentioned in the user guide (2 ones) are the same as “pafr” has in his own guide with the only difference: my user guide is in Russian
    The trouble is the phone is not working in Canada. It writes "No network coverage". The phone worked in Russia but it isn’t in Canada.
    When I was buying the device, I asked the vendor whether it would work in Canada, and they answered YES. Having faced with the issue, I asked Nokia Support (at their site) what’s wrong with it. But they answered the phone should work and no actual help.
    A friend of mine has got Motorola. He also bought the phone in Russia and has international roaming here, in Canada. He took his phone with him to Canada on a business trip too. It works. I borrowed his phone and inserted my SIM card into it. With my SIM card inserted in his phone, the network was immediately found (Rogers). Our location is Belleville, Ontario. Then we put his SIM-card in my Nokia 1208 and it didn't work either. So, it's not an issue with service provider. The service works indeed. It's the issue with the phone itself (Nokia 1208).
    I’ve got an expert opinion that the phone is dual band but it comes in two versions, one for USA/Canada (GSM 850-1900) and one for Europe (GSM 900-1800). Obviously I have the European version, so... To my deep disappointment, Nokia Support (neither Canadian nor Russian) did not manage to agree with that and continue answering my phone should work in Canada. That’s all “help” I have had from them. This is extremely strange that Nokia look incompetent with their own product.
    Do you know if there’s any chanсe to make my phone work? My be it needs some kind of initial activation, so that it could work then? How did “pafr” make their Nokia work?

  • C2-03 compatible on US mobile networks?

    I recently purchased the Nokia C2-03 for a senior staff member since Nokia advertises it as a quad-band phone.
    GSM 850/900/1800/1900
    However the phone does not recognise any sim card inserted in the device when in the US.
    Is there any setting that needs to be changed to allow the device to communicate with US mobile networks?
    Thanks.

    Hi Kashee,
    Thank you for your post. Just to confirm that Nokia C2-03 is in fact a dual band device not a quad band and it can be used in those regions Asia-Pacific, CHINA, Eurasia, Europe, INDIA, Middle East.

  • GSM and EGSM

    Dear Posters and Readers,
    I am planning to buy the N900 from the USA to use it there eventually, but I will be traveling to Lebanon (Middle-east) during the holidays and I am going to buy a new SIM once I get there for it is much cheaper than roaming.
    Now I read the specs on N900's page, and I read the network specs of the providers in Lebanon, the thing is that N900 supports "E"GSM on all bands 850/900/1800/1900 and providers in Lebanon broadcast on GSM 850/1800.
    My dilemma is, will the N900 connect in Lebanon looking that it supports EGSM ?
    Is EGSM backward compatible ?
    I asked Alfa and MTC (the 2 providers in Lebanon) about that, Alfa peeps said it was okay and it's going to work just fine, but MTC peeps said it won't work. Then I said i'd ask the official resellers of Nokia in Lebanon (there were 2 of them a month ago, now they're three, so I decided to ask the oldest 2), MeaTel peeps said it won't work, FCC peeps said it's going to work just fine.
    So which one is it ? Should I worry about this or not ?
    Any ideas are appreciated.

    E-GSM stands for Extended GSM. As the name suggests, it is an extended version of GSM in terms of the frequency bands supported.The underlying technology remains the same.
    Therefore, your N900 will work just fine in Lebanon. There's no need to worry.

  • No Carrier on GSM 1900 ???

    Just got my 6131 Quad Band phone, brand new put my SIM card in it, the pone boots up fine without glitches, but does not see the sginal or detect operator networks, I am in Canada the GSM here is 1900, I had my older nokia 6610 working like charm without problems, what could be the issue? I called Nokia Canada but they said we don't support this model!

    Hmm.. your phone should work coz it covers the frequency there..
    Try pressing the "#" and then call..
    Your phone should be requesting a signal from your network..
    Try also using other SIM card (Other Networks' SIM card also).. If this doesn't work, your phone has a problem..
    " Your Nokia Handset operates on GSM 850/900/1800/1900 MHz frequencies. Canadian GSM carriers offer network service in the 850 and 1900 MHz bands. This means that your handset will operate on the 1900 MHz bands of the Canadian networks. Users may find that network coverage may not be as comprehensive in areas that also use 850 MHz band networks, such as in more sub-urban or outlying areas. Other users will not experience any difference in their service. For example, the handset will operate on all of Fido’s network as it operates entirely in the 1900 MHz band. "
    Hope this article from Nokia helps..
    Your phone's cool and new!
    cheers.

  • NO 3G RECEPTION? IS YOUR SIM CARD 3G or 2G? There's your problem.

    Dont mention it

    This comes from the technical departments of Orange as well as swisscom, which are the two carriers selling the iPhone here:
    "The SIM card on swiss GSM/UMTS Networks have as much to do with 3G reception as the color of the sock you are wearing."
    "All SIM cards issued in the current millennium will be fully 3G capable no matter what phone you put them in." (That's a direct quote from our swisscom technical contact, he's an leading engineer with the mobile networks group. He's also the one with the socks quote, similar things have already been said here in the discussions.
    "All SIM cards issued by Orange Switzerland since we started mobile service are fully 3G capable, but getting the latest generation won't hurt" Orange
    FWIW I already had the latest gen SIM card when I got my iPhone and 3G reception was between abysmal and non-existent.

  • IPhone 3G Reception Problems - anyone taken it apart?

    Not sure if the rest of you are having issues loading the long thread about this, but it's gotten so long, I can't even get it to load anymore - it also keeps saying it's running some script. Thought I would start a new thread with a new question...
    There's all this talk of poor 3G reception - I agree, it's pretty bad. I was on a conference call yesterday driving from Downtown Houston to the Galleria - fairly big urban city with what's supposed to be massive 3G coverage - dropped the call 3 times - once in my parking garage, once getting on the freeway, and once arriving at the Galleria. I had 3G on. The Apple Store Genius told me he leaves 3G off and only use it for web and data.
    I also noticed that every iPhone in the store was on Edge, none on 3G - couldn't get a signal.
    There still seems to be great debate as to if this is an AT&T issue or an Apple issue - some have said perhaps a problem with the antenna - well, has anyone taken the thing apart to see if there's an antenna issue? I know Gizmodo or one of them dismembered an iPhone, I'd of thought they'd see something.
    I do notice that if I put my hand on the bottom of the phone, I definately lose signal - move it away and the bars go up - is that the phone, or AT&T - or both?
    Sorry for rambling - I just wish someone would be able to do a little more accurate testing than all of our anecdotal thoughts....

    Have you had an AT&T 3G phone before?
    You can not compare 3G reception to GSM reception. It's apples and oranges.
    The 3G network is completely new cell sites. It has far less density than the old GSM network. In other words there is not one 3G site for ever 1 GSM. It's more like 1 3G for every 5-6 GSM sites (or even worse, depending on where you are.)
    Have you ever had a 3G AT&T phone?
    I haven't had a dropped call, but admittedly I haven't spent a lot of time on phone calls since I got it. But I had calls drop occasionally going from 3G to GSM on my last two. Usually it didn't happen, but there were a few places I could get it to happen every time.

  • Would the 928 work on a GSM carrier if unlocked?

    I have read the specifications of the 928 and it says that it works on all the same  frequencies that AT&T and T-Mobile do?  Does that mean that a person could get an unlocked one and use it on a GSM network? If anybody has any knowledge of how this works let me know.
    I'm new to the forum, but I have to say that I loved the Lumia 900 I had and the 822 is awesome as well.

    It will work on these bands.
    2G Network GSM 850 / 900 / 1800 / 1900
    CDMA 800 / 1900
    3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
    CDMA2000 1xEV-DO
    4G Network LTE

  • Switch b/w edge and GSM on Blackberry Curve 9380

    Hey few days back I bought Blackberry Curve 9380. Basically I'm new to Blackberry Universe.
    Generally when I'm at home, I prefer to use GSM only coz I have Wi-Fi. But when I swtich off data usage, connect to Wi-Fi, the Browser and other internet applications say that they are unable to internet. 
    Also guide me how to switch b/w GSM & edge network...
    Solved!
    Go to Solution.

    First Your need BIS - Blackberry Internet Serives subscription from Vodafone IN, this is the unique feature which seperates other mobile devices from Blackberry.
    Browser, Facebook,twitter and all other apps require BIS subscription. Only appworld will work in Wi-Fi mode.
    You can change the Browser settings to Hotspot to work in wifi, but i think in OS 7 it will detect automatically.
    if you have BIS subscription 3G is free.
