3g problems

[JJC]

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 (http://www.gsmworld.com/roaming/gsminfo/cou_ph.shtml) 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.

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 ?

[JJC]

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. ;)
