Question: Is it possible to use only wifi with skype with no contract?
Document: I recommend this phone to anyone who doesn't want to be sucked into a contract extension by att. The price offered in Amazon is a lot lower than what you would pay for the same phone at att retail shop (without contract). The seller delivered the product promptly and the product was in great condition.
there are more cons then pros...the wifi connectivity , battery back up are very poor. though the product sent was neat and good looking i had the above mentioned serious problems
This phone is absolutely amazing. The only problem i am having is that i cant sent pictures if i figure out that, if its even possible, then this phone is perfect. All the nokia extras like nokia drive(navigation) and nokia music make this a great deal. Good price at the moment so totally worth it for me.
my carrier is tmobile and it says that this phone is at&t LOCKED. so im not sure if i could use this phone using my simcard.
It's a nice experience with this windows phone and love to continue with that... stylish, productivity, easy to use and it's a great product...
Call quality, ease of use, screen clarity, responsiveness, syncing: this phone does it all well. If you are a Windows user this is the phone to own. I highly recommend it.
Tons of Apps out there. Calendar is easy to use and I can actually hear people talking on the other end. My husband is going to get one when his upgrade comes due. A great buy!
The original box is unsealed, and it is old and broken. However, lumia 900 is great and I am a big fan of nokia. I like the WP7 although it can not upgrade to 8, but I think it is enough for me to use it.
This product not only came fast, it came ready to use. All parts worked great. I LOVE my new windows phone!!! I was even able to get it unlocked by calling ATT so don't let that stop you from buying!!! !
I've been bluetoothing from the old phone to my PC, then from my PC to my Lumia, then moving them around to where I'd like to have them rather than where Windows wants them. And forget about migrating EMAILS, text and mms  - the support pages tell you to back it all up on your PC and use the 'appropriate software' to work with them on it.
Answer: yes
