We are both able to make and receive calls and send and receive text messages, but we can not access the internet. When we first turned our phones on, we did not get the option to register our mobile phones and now we are unable to change any privacy settings. If anyone knows how to resolve this problem please tell me. We have just spent the last hour or so navigating around the T-Mobile site looking for answers, but we were unsuccessful. Thanks heaps!

  • Hey, I'm using a sidekick 3 right now here in the philippines. When I bought the phone from GH they said this (Sidekick 3) is the only sidekick that can be used here. It doesnt need to be opened here just put some code in it and its all set! Its a huge hassle though when reception is low, coz you have to put the code all over again. But pretty much its functional for text messaging, calling and photo sharing.

  • i`m planning to buy this phone. someone said that they can open t-mobile sidekick here in the Philippines. do u think it can be unlocked? whats importnt to me is that i can text and call and send pictures. please answer. THANKS!!!!!

Please ppl..For answers hit me up at aim : Ramgue18...Pleaseee!! I'm soo desesperatee

  • wat does an unlocked t-mobile phone mean?can someone pls explain? thanks :D

  • This phone is not goin to work properly anywhere but in the US. I've worked for TMobile customer service and it is the company's (TMobile) policy that unlock code for this phone cannot be given to any customer. Others may say that theis works in some countries, but will always give you the same problem. Sidekick is a phone that is exclusively for TMobile only. Believe me, it really is a cool phone but it will only give u a headache. =)

  • Only these steps make it work but the problem is that u have to repeat these steps every time when u switch on the phone

  • Yes, it works in other countries, BUT, it doesn't work full. WHY!?, I've one, and I'm looking for unlok my cell phone, I WANT TO USE INTERNET on my phone!!! THANKZ K

  • did u hav to unlock it or just these steps made it work out of the box?

  • hello :) i'm from the Philippines too! i have plans of buying this phone but Im not sure if anyone here in the Phils could do such. So is your sidekick unlocked na? i'd love to hear your comments about this phone :)

  • To make it work on other countries (I've tried it in Pakistan) follow these steps: 1. After you start you phone, go to Settings > Sim Center 2. Then, if your SIM allready has a PIN just change it. if it dosn't have then create one. Then goto Network Options and select Scan and Manual Select and Then select your Network. It will Start Working

  • To make it work on other countries (I've tried it in Albania and Kosova) follow these steps: 1. After you start you phone, go to Settings > Sim Center 2. Then, if your SIM allready has a PIN just change it. if it dosn't have then create one. Change it 3. Now you should be able to see the network bars on the upper right side. If so, proceed. 4. Now go again to Settings > Network Options. Scroll down and select Rescan and Select Manually. Select your operator. Thats it.

  • well i got a hold og this phone yesterday and it was offered to me in such a very low price but this baby will not work in asia! I'm from the Philippines and im very confident with our Filipino phone technicians here.. but they're having a hard time figuring out this phone! the swivel display mechanism is scary! like it could fly away anytime you move it! haha! it's also too long to be place on your pocket.. it's like a mini version of Sony PSP.. haha! well still im hoping i'll be able to get a use of this phone! hi to everyone! Gsmarena Rockz!

  • i like this phone..... how to open my gprs???

  • Hi guys can any one please tell me that does it work with indian sim:-):-) and what would be it's cost in indian rupees:-):)

  • yes

  • hey :D :D i really want a sidekick :D i could get one from ebay for 220 euro from HongKong do you think it is worth it and would it be safe getting it from China ?? PLEASE HELP guys :D :D

  • does this phone needed a sim card or not?

  • im getting this phone today im really excited but at the same time im worried that is not gonna work really well

  • I LOVE LOVE LOOOOVE this phone. the internet is pretty fast, texting is soo easy on the smooth keyboard, and the camera served as my own "digitaL" camera for a couple months too! this phone serves as my mini computer because of the instant messaging services as well. i don't really have anything bad to say about this phone other than it randomly crashing when you have too many things running at once. i COMPLETELY recommend this to anyone who is thinking of buying one. and don't worry if it breaks, t-mobile has exceptional customer service and will replace it within three days. you can't go wrong with this phone. love love love it.

  • Plz help me! I need a iwireless phone that has a sim card, i deal locally only, plz help me anything will contact me at [email protected]

  • I've had mine for a year and a half. going to upgrade to either the Memoir or the Curve cuz I dropped it a lot so its pretty beat up. But I never used a phone case and have dropped mine on concrete dang near everyday cuz I work in a warehouse so I'd say it was pretty durable. No scratches or cracks in the screen, just scapes and scratches around the edges.

  • This type is better than sidekick 3...

  • Anyone having problems getting ringtones on their phone? It keeps saying unsupported media type

  • honestly im very hard on my phones...i had to buy mine off of craigslist since the phone i upgrded to i broke. so i completely understand ur need for a durable phone. like my posting said ive had mine for 4 months...the only thing that has happened to mine is normal wear and tear...ive dropped it a few times and nothing happens.

  • i just got the phone yesterday and i must say that i love it!!! but i am worried about the durability of this phone. i tend to drop my phones a lot especially at parties when i've consumed too much alcohol. the swivel part's really cool but then it feels a little fragile so im scared about it too. but overall, it's an amazing phone.

  • ive had the lx for about 4 months now. i have to admit that heavy texters, or internet browsers wont like the phone due to the horrible battery life. i have to charge my phone every night. but all in all a pretty decent phone. very simple to use once you get use to it. pics arent the best but come out pretty good. the music player sounds pretty good, only thing about the applications you can download that i dont like is that you can only store so much, without having to delete something jsut to dl another app. overall a pretty damn good phone. i never have probelm reception or anything. also who can beat the 19.99 UNL data plan that tmobile offers? i work for att and if i had a similar phone i would have to pay 50.00 bucks just to have unl internet, email and Mssging on this phone. so kudos to tmobile for that!

  • retarded phone....

  • Hey is this good??

  • The LX has a bigger/better keyboard, a bigger screen (the Slide's is pointlessly small), and the LX is far better looking and has better build quality.

  • The flippy mechanism?!!! lol

  • Can anyone tell me if there is any REAL advantage the LX has over the Slide?
