S710 with a Three SIM card

Hey guys,
My girlfriend bought a s710, and is on the UK Three network.
The phone is meant to be SIM free, and works fine with my Orange SIM card in, but not her Three SIM card. It says the card in not valid.
Any ideas? Is the s710 not capable of using the SIM card?
htc-s710
if the unit is branded htc then its sim free 100 %
if its branded orange spv e650 then its locked to orange uk
and then ur job will to ask orange uk for unlock code or to unlock it via http://www.imei-check.co.uk/e650unlock.php
gd luck
Cheers Motin.
It's branded HTC, bought from www.handtec.co.uk as a SIM free, but still refuses to accept her SIM card at all.
htc-s710
u should make sure all sim cards are clean from scratch
if they are u r off to send it back to htc for replace there should not be any problem with the unit and it should except any sim card
thanks
I don't know but I thought three was only a 3G operator? And the S710 is not a 3G phone. could that not be the problem?
htc-s710
i can only confirm to you i am using an orang 3g sim card on my htc -s710 and i have now tried 2 more sim cards that are 2.5 generation and all working 100 %
thanks
Yes but if it is as I think that tree only has a 3G network the phone won't work there since it is not supporting 3G?
htc - s710
now i fully understand you
my dear the 3 network is only 3g so any sim from 3 network will work only on a 3g phone !!!
thanks

Confused and Stressed Sim with Wifi?

Hello all,
i got my Xoom from my friend. He told me that it is a WIFI Xoom. it is mz604 but it has a Sim Card hole ?
What does it for ? i live in Turkey. is it for 4g or cdma only or it is only for decoration ?
i succesfully flashed Turkey FW and mobile network is disabled. i checked out Turkish xoom when you take out sim card its mobile network is disabled too.
i wonder that sim card socket is working or not ? if it is working i can transfer it to 3g (i think) but if it is cdma or 4G or whatelse it is only a fantasy.
What do you think guys ?
The SIM card slot is not connected to anything in the WIFI Xooms, however, the SD card slot is in that same area.

[Q] hardware differences between US verizon 3g and UK 3g

Hello all
i have a verizon 3g xoom. it's not upgraded yet. i live outside us
about the UK 3g xoom, can it operate 2g sim card? for sms, gprs or ...
how about normal 3g sim cards?
is there any hardware difference between mine and uk one?
may i operate my 2g sim card on my xoom? how about 3g?
when i put sim card nothing happen. i just tried 2g sim card
our 3g operator is not started selling sim cards ... but we have 4g operator.
if i install uk xoom's rom on my own, can i use sim card?
is there any mini pci-e card that i can use my sim card with it? (self upgrade xoom with custom mini-pci-e)
please help me. i need some information. i'm confused.
http://forum.xda-developers.com/showthread.php?t=1263634
how about this thread? i've done that but dont work for me. there is no signal, i think it didnt recognized my sim card.
if i install the mini-pci-e card that motorola installs on xoom during upgrade, can i use sim card for 2g/3g ? (sms or internet)
i have found this : "If you bought your Xoom from Verizon, it will have no SIM card slot. Verizon's CDMA network doesn't use SIM cards. Also, if you bought the Verizom model, it will only work on Verizon, and not another carrier. There is also a WiFi-Only Xoom, and it does not have a SIM slot."
here : "http://www.ifixit.com/Answers/View/53440/Why+I+can%27t+find+3G+SIM+Slot+in+my+Motorola+Xoom"
but mine have sim slot with a plastic sim on it.
The Verizon 3G Xoom does have a sim card slot but no hardware inside to read the sim card. That is what the 4G upgrade was for, to install the hardware necessary to utilize the sim card for the Verizon 4G LTE network.
I don't know if anyone has gotten a Verizon Xoom working on any other carriers network.
Theres pix of the inside of my Uk3g Zoom somewhere...
