Hi. Newbie in this forum. Bought an htc tytn from u.s. but am from Phil using smart carrier with gsm band at 1800. after going thru sev topics, properly identified device as Herm200 rom:1.18.255.3 07/22/06 extrom:1.18.255.106 radio1.03.03.10 protocol32.34.7010.01H.
All phone features working perfectly except for 3G. Smart carrier people cannot help. What could be wrong. Vendor says 3g works on 2100 band. Confusing statement. What can be done? Connects to umts but when video call is pressed will not connect.
Which carrier are you on again? Smart Carrier? .. From what I know no carriers in the US support video calling .. Also, Cingular is the only GSM carrier in the US with 3G which runs on the 1900Mhz band ..
also .. what does your phone display while connected "G" or "U" ... what are your phone band settings .. can you also goto dslreports.com/mspeed and see what speeds are you getting ..
According to GSM world SMART (a Philippine operator) uses UMTS 2100, which your TyTN does definitely support.
Have you checked if your SIM card is 3G-enabled? Most 3G networks require special USIMs for 3G usage.
I just learned, that Cingular uses UMTS 850 and 1900 to be exact. According to the American HTC website the Cingular 8525 supports "Tri-band UMTS/HSDPA high speed wireless data network support (2100MHz and 850/1900 MHz), Quad-band GSM®/GPRS/EDGE worldphone".
Does anyone know if there is a special hardware version, that supports UMTS850 & 1900 or will my European TyTN work on those networks, too?
TyTN is tri-band UMTS .. 850/1900/2100 .. so it should work on these networks without any issues ...
And my bad .. didnt realize that you are trying to use the TyTN in Phillipines ..
You should also check, if the called party has a 3G signal, while you call him. Further make sure video calls are activated by your network operator.
3g problems in the philippines
Everything you guys mentioned in order(am in a 3g area calling a 3g enabled party with a 3g sim card). Even the tech staff behind Smart Communications cannot make it work. Displays U and u. But video call cannot push thru even if pic on front camera shows. There is 1 thin line( or command?) stopping it from connecting. My last option is to borrow my friend's unit and see if her unit's 3g works here then it's my device that's a problem. Thnks for the input. Keep it coming.

Hi. I don't know how they did it but Smart Communications did it! Apparently and ironically their 3g sim card is not compatible with the htc tytn but their regular sim is. Thanks all.
are u using 3G now in Phil ?
Is there a Globe perpaid 3G simcard ?
3g problems no more
Hi everyone. After my first thread i have finally got everything on my tytn working: 3g, mms, internet, phone. The problem was on the settings. Smart and Globe, the primary carriers in the Philippines can both work on the phone if the settings are right.
sectorlord,
yes there is 3g and hsdpa along with gsm and gprs and wap in the philippines. and yes you can buy globe prepaid 3g sim card.
glad to hear you've got your problems solved jjc!
hi
i have here few PCS of S5630L
its same phone but bands are not the same.
HSDPA 7.2 850/1900MHz
anyone think it can be changed via software ? or its a hardware issue ?
if so can i change bands filters ?
thx
anything ? anyone ?
it can never be done,
it is the internal radio which transmits and receives frequencies,
which is a hardware thing,
if i got you correctly S530L is CDMA and you want a GSM band

This model is not cdma, irs gsm model fits to some countries like brazil and argentina.
so this phone works only on quad gsm 2g network with no, but on 3g networks it works only on 850/1900 and i need 2100
On older nokia phones we changed anttena duplexer and bands filters and it did the job.
On newer phone like i9000 we can change bands via programing menu.
I just wonder if it can be done even with hardware changes.
Thanks
Anyone ??
I tried *#*#197328640#*#* but not working
Hi all,
I am desperately looking for a solution to the above problem.
Background: I moved about a year ago from Germany to Canada. My HD2 worked well with the sim card from Telefonica/O2 on the network over here. The phone itself is not locked but branded. Anyway when I tried to change to a Bell sim card it did not want to work. So I looked up the frequencies. My HD2 works on the following frequencies:
GSM1800
GSM1900
GSM850
GSM900
W-CDMA(UMTS)
The providers over here have the following frequencies:
Telus (including Koodo)
2G
CDMA 850/1900
EVDO 850/1900
3G (and fake 4G)
HSDPA 850/1900
HSPA+ 850/1900
UMTS 850/1900
WCDMA 850/1900
1x EV-DO CDMA2000
Bell (including Virgin Mobile, PC Mobility)
2G
CDMA 850/1900
EVDO 850/1900
3G (and fake 4G)
HSDPA 850/1900
HSPA+ 850/1900
UMTS 850/1900
WCDMA 850/1900
1x EV-DO CDMA2000
Rogers (including Fido, Petro-Canada Mobility)
2G
GSM 850/1900
GPRS 850/1900
EDGE 850/1900
3G (and fake 4G)
HSDPA 850/1900
HSPA+ 850/1900
UMTS 850/1900
WCDMA 850/1900
I thought at least that with the frequencies like CDMA and GMS matching I could use any provider that works with these frequencies. Obviously I was wrong there Anyway I want to use the phone. Can anyone out there help me and get me the information which provider would work with the phone? I would use anyone as long as I can just use my HD2 again.
Thanks so much for any kind of help.

EU HD2 will work on gsm in Canada but looks like will not match 3G wcdma used in Canada.
I used my EU HD2 in Canada on Rogers for a week & was fine on gsm.
Do check in phone settings to see bands are set to auto or gsm only, if set to wcdma only then will not connect to anything.
Not much you can do on 3G issue as hardware & not changeable, the australian Telstra HD2 & USA T-Mobile Hd2 is more compatible as hardware supports the 850,1900 & 2100 wcdma bands ....

I was with my German sim card also on Rogers. I just did not know if the phone would also be able to handle the local sim card. I will try Petro Canada or Fido. Rogers is a little expensive. Anyway thanks. Gives me hope

Hey all,
I just wanted to give a feedback on my recent experience. I yesterday checked at a Fido shop and I can confirm that it works. I now can use my HD2 again :good::victory::victory::victory::good:
I will get a sim card next weekend and then will see how to update my phone to something more current.
Thanks again for the tip Mister B

Hi everyone,
I got a new Galaxy S5 (sm-900-w8) for my birthday. The device was bought in Canada.
It got unlocked for international usage (entered the 8 digits pin-code) and it worked PERFECTLY for 5 days.
After those 5 days the device got turned off because of the battery died. Recharged it and turned it on, and suddenly I get "Unregistered network" message on my lock screen.
Tried 4 different SIM cards from 4 different providers. Still, nothing.
The device DOES recognize a network when I turn it on, but after I'm trying to make a call 2 times (and gets a "call ended" message), it goes back to "Unregistered network" message or "Emergency calls only" message.
Please note that the signal bar is full.
Any idea how I can fix this problem?
Also, I rooted the device after the 3rd day. Does it mean I don't have my warranty anymore?
Thanks.
You didn't provide enough information for us to know what is going on.
The unregistered network simply means that your phone isn't detecting a valid SIM card. First try your SIM in another unlocked phone to see if the SIM card and or your account appear to be working. If not, then contact your carrier to check your account settings or replace the SIM card if necessary.
If the SIM works in another phone but not yours then we'd like to know where you bought your phone as the number one suspect would be IMEI blacklisting. If that isn't the issue, then the first thing to try for any unexplained anomalous behaviour is to wipe the system cache from recovery mode.
If the problem persists then you need to start troubleshooting which is nearly impossible without a detailed description of your situation. You didn't even tell us any basic info e.g. what carrier you are using, whether the SIM works in another phone, what S5 model, firmware, a step by step description of the changes you made to your phone, etc.

Thanks for the answer.
Now that I know which information you need:
- I tried my SIM card on a different device (Galaxy S3). It works perfectly.
- Also, as I mentioned earlier, I tried 3 additional SIM cards, all of them works perfectly on other devices, but not with my Galaxy S5.
- The device was bought from Rogers in Canada. I talked to them, they said it isn't blacklisted.
- I already tried to wipe the system cache from the recovery menu. Didn't help either.
- I wrote the model in the previous message: SM-900-W8.
- The current carrier is Golan Telecom in Israel.
- The firmware is 4.4.2 that came with the device. Didn't have the chance to update.
The step by step description you requested:
- I rooted to device.
- I unlocked it using a code that was given to me from some kind of shop in the mall (wasn't there, my gf took care of it), but it worked perfectly.
- The device worked well for 5 days, then the battery died and after I recharged it the problem started.
- If I disconnect my battery for several minutes and connects it again, the device DOES SHOW that it is connected to the network ("GOLAN T"), but if I try to call, after several seconds it disconnects and the "Emergency calls only" or the "Unregistered SIM" message appears.
- Tried reseting it to factory settings and to wipe the device's cache from the recovery menu. Didn't help.

Bingo. That is why you can never have too much information when troubleshooting.
Until proven otherwise, your problem is almost certain to be the fact that you are not using the S5 model that your carrier expects. Most Israeli carriers use the 900F model and you bought a 900W8 instead. The W8 is not intended for use in the middle east and has a different spectrum allocation than the 900F model.
Ask your carrier to spell out exactly what frequency bands they use in their network. More than likely one or more bands is missing in the W8 and that will be your problem. Other possibilities include region locking, which is Samsung trying to block you from doing exactly what you are attempting.. buying a phone in one country and using it elsewhere. You should also check the carrier blacklist (this is not the same as the IMEI blacklist).. but rather a roaming block that may be interfering because you are using the phone in a country that it wasn't intended for.
And possibly.. although unlikely, your carrier may block foreign IMEI numbers. You'd have to ask your carrier if they have any restrictions regarding handsets that customers purchase from third party sources.
There is one possible anomaly here. Your first post said that your phone worked for 5 days before failing. Was that 5 days in Canada or Israel? If Israel, that makes the last possibility more likely, although it could also be attributed to other factors.
Even though your SIM card working on a different handset tells us that there is some incompatibility between your phone and your carrier's network, you may still want to open a technical support ticket. It's possible that your carrier support department may have run into this issue before and have an expedient solution. Perhaps something as simple as needing to manually add the correct APN info.

Hey, thanks again for the answer.
The 5 days that I mentioned (when the phoned worked perfectly) were in Israel. The phone was never used in Canada, so do you think the frequency issue is still likely?
I already talked to my carrier, and tell you the truth, the carrier doesn't sell any devices (at all), so I really doubt they will block my device.
Again, they didn't even knew I changed it. They checked it out when I called them, and they said they never block any device - I did mentioned that the device was from Canada.
And again: I tried SIM cards from 4 different carriers (except for Golan Telecom, I tried Cellcom, YouPhone and Hot Mobile).
Is there any other information that you need me to provide?
Just tell me what and I'll give you the information you need.

BTW, I've checked the APN info, but it's just needed for MMS and for the 3G internet.
Tried with that configuration and without, it didn't matter.
Oh! I just remembered one more thing.
I succeeded browsing the internet VERY slowly, several times (it wasn't WIFI of course). Super-weird.

That datum confuses the issue, but yes the ostensibly missing frequency bands are still the most likely culprit. Particularly since you tried multiple known good SIM cards in your phone. Something is conflicting between your phone and your local networks. And by far the most obvious cause is the spectrum allocation. Meaning that it may work erratically (or for five days) but can fail when the system tries to use the missing band(s).
Less likely, your local carriers may be conflicting with something else in the phone. Or it could be a random hardware failure, although that is very improbable. If it was a hardware failure, I'd think more in terms of a damaged SIM slot than semiconductor failure. Troubleshooting is all about ruling out possibilities and looking for patterns. So you need to work though the list of the most obvious candidates. For a start:
- Find out what frequency bands your carrier uses. And compare that to the W8 specs (Google search: sm-g900w8 specs)
- Check the roaming /region lock blacklist i.e. /system/csc/customer.xml and confirm that your Israeli carriers are not listed in that file.
- Find out what your carrier's APN information is and confirm that your phone has the same settings.
If you don't find a solution there, you should wipe your system cache from recovery mode and do a factory data reset. And failing that even write a full stock firmware image to the phone again - the latest firmware available just to cover the slight possibility that it could be a firmware bug.
And while not a panacea, you should still open a support ticket with your carrier. Don't get them mired in a long set of I've already tried this and this and this.. Just tell them that your phone worked fine for 5 days and now gives an "unregistered network" error. And that your SIM continues to work in other handsets. That should spur them to look into your account settings and hopefully identify anything that may be conflicting with your W8 phone.
And as a last resort, I guess claim it under warranty. If you used Towel root your warranty is probably still intact. You can boot to download mode or install the Phone Info app to find out your Knox flag status. If it is 0x0, then you only need to restore the stock firmware and you should be fine with respect to warranty.
If your Knox flag is 0x1 for any reason, Samsung will raise a stink about it. A lot of carriers don't care about Knox with respect to warranties thought. I don't know Roger's position on that point but in any event don't make a warranty claim directly with Samsung if you have a 0x1 flag. Make a warranty claim through your carrier (presumably Rogers) instead.

I'll check all of those and will let you know.
Can't call my carrier on Friday here in Israel, but I'll do that on Sunday and I'll update with details.

Nope, not really all that weird. It sounds more and more like you are missing a key GSM frequency band.
Nevertheless you should check all of the possible culprits.
Good luck

Quick search using google:
According to this: http://www.worldtimezone.com/gsm.html, Golan uses 3G 2100 frequency, which is supported according to this: http://www.samsung.com/ca/support/model/SM-G900WZKABMC (tech specs are expendable at the bottom).
Other frequencies seems to be supported as well. Actually, all the frequencies of the Israeli carriers seems to be supported.
If your handset supports all active frequencies that is great news, but you still need to work through the rest of the list of things to look into. Also, if you know anyone local with an unlocked 900F S5 phone, try your SIM in their phone.
Specs for Israeli 900F and Canadian 900W8, differences in bold.
You need to confirm that your carrier does not use the missing frequencies i.e. B8 (3G GSM 900) & B20 (LTE 800)
SM-G900F
2G GSM B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz), B14 (PCS 1900MHz)

.
OP this may sound ridiculous but go into your System>About Phone and check for your imei... you can also do *#06# hit send on your dial pad...
If your imei shows 000 or something weird other than the one that is printed on the sticker under the battery or box then you have a defective phone. I usually see this Unregister Network thing happen to quite a few Samsungs over the years, starting with the S2. You may have done something and caused the IMEI to get lost/wiped in the EFS.
The best thing to do in this case is you have to have the IMEI rewritten. This may be really easy if there is still an EFS backup on the phone or if it is still accessible. Otherwise at the time of writing this I think both the Octopus/Z3X cannot write IMEI on the S5 so taking it to repair shop can be pointless until it does.
Worse case scenario is your actual baseband chip is screwed.
Anyway, check to see if your imei is there. No IMEI = network cannot register you on as you device doesn't exist.
