Tango phone arrived within a week in the USA. It was well packaged, the 2nd extra battery it comes with is a plus when traveling. I placed the T-Mobile pre-paid sims card from my old phone in the Tango phone & it connected immediately. I called some of my contacts & it worked flawlessly. Since it has dual sims card capability I intend to add a 2nd sim's card from another carrier as soon as I choose the right plan. Your sims card from your present GSM phone or new sims cards from AT&T & other GSM sim's card carriers should work on the Tango phone. The home router wifi & mobile hotspot wifi were connected next & the wifi signal from both were picked up smoothly by the phone. Then the Jawbone bluetooth ear/voice piece was next & the signal was also picked up quickly. The Android OS is very user friendly & is easy to navigate. The touch screen is precise & it compliments the QWERTY keys. I prefer QWERTY keys it is just my choice. The keys light up for night use. Shortcuts with a couple of key strokes can be setup for all the applications such as calendar, contacts, browser, camera, etc... Everything tested thus far has worked great. I used my home wifi with the phones Opera browser to go to www.lighinthebox.com it quickly went to the site. Then I used the store search and keyed (phone Tango) the store ad for this phone popped up, nice. The screen is clear & easy to read.
Do not expect much help from the instruction manual. Not many manuals are helpful anyway. Most of the negative reviews I read are from users who are not familiar with hi-tech products. If you are not used to how they operate you will have problems. But it is usually not the product it is the operator that is the problem. Be patient, have a cup of java & you will enjoy your toy. A frequent complaint is battery life. Turn off everything that is not being used, wifi, bluetooth, applications that run in the background etc... even the phone when your not expecting calls.
I am very satisfied with the Tango phone & would buy it again. It does everything very well that I need to do with it.
Mainly to use it as a dedicated phone with ease of data input & dependable call connectivity. The extras are good to have if needed. I have only used it for a week but judging from the solid build & feel of this phone I expect it will last me a nice long time, which makes it a good investment.

What kind of GPS does it have? Does it need internet conection to access gps? Do you have any kind of protective case for this model? thanks a lot!

I bought this phone for my sister , the item was shipped withing three days as promised from the wa0rehouse with no problem . I got the item in googd condition and my sister loved it . Great Job guys , I will recomend your services to anyone i know .

Quite good device for nice price. Only one bad think is battery life time. You have to charge phone every day.

Good for texting and games. Poor performance when used to access the internet.

J'habite en Guyane Française et j'aimerais savoir en combien de temps ce produit pourrait mettre livré si je le commande et quel sera le montant des frais de livraison

Perfecto, este telefono TANGO ha cubierto todas mis espectativas. Lástima que los pagos de aduanas sean tan caros y que el manual sea sólo en ingles.
Gracias
