    Unlocked  Samsung Galaxy Tab 7.7 WiFi+3G P6800 16GB and T-Mobile Sim Card?



      I am a little new to android, smartphones, and tablets in general so I hope someone will be kind enough to help me


      I am thinking about buying an unlocked Samsung Galaxy Tab 7.7 WiFi+3G P6800 16GB. Is it possible to obtain a sim card from T-mobile with a phone number? It is my understanding that this tablet has a built in phone capability over 3G, but I don't know if sim cards come with phone numbers. Also, assuming I can get a phone number and sim card, can I buy a pre-paid amount of minutes or a pay as I go plan to use for phone conversations and only use the device as a phone when I feel like it? Lastly, could I also sign up for a pay as I go or pre-paid plan for data in conjunction with or separately from the talk plan?


      Hopefully someone will be able to help me understand exactly what I need to do.

          Thanks for the post Robert as far as using that tablet on our network it will work however you will only get 2G and not 3/4G due to the fact that it uses the 1900/2100 for UTMS and we use 1700/2100.  That being said you can activate a prepaid sim and then apply an internet pass to the account here are the details of that (at the bottom under prepaid)



          If you have further questions or if I missed anything please let me know.

            Hello Keith,


            Thank you so much for taking the time to reply; I really appreciate it. I was starting to wonder if I would get any reply at all when I saw how many people were viewing my question and not having anything to say :-)


            Anyway, I am still confused, but the fog is lifting a little. I saw the pass for broadband, thank you. But what about being able to make phone calls? Will I be able to do this on the T-mobile network? I purchased a T-Mobile sim card activation kit and it is on its way to me. It should arrive the same time I get the phone, so I will try to make a call with the included minutes. As far as the broadband goes, do you think SKYPE would be a good option for telephone calls through the broadband connection if the cell calling doesn't work?


            Also, the UTMS issue is way above my knowledge level, however I think I found something, although it was under UMTS, that seemed to indicate that the AT &T network uses 1900/2100, but I am really not sure. If they do use 1900/2100, would that mean I would be better off getting a sim card for their network for both data and cellular?


            I realize that you are associated with T-Mobile, and you probably want to see me use T-Mobile, however if I am limited by the capabilities of the phone itself, I hope you will consider steering me in the best direction.


            Thank you again, very much!




            By the way, I don't know if this will help, but here is some info on the phone/tablet:

              You are very welcome sorry it took so long for us to catch you, now on to the meat of the post.


              First off we would rather see you happy with another carrier than unhappy with us and you will see that as I continue you are correct UTMS is the 3/4G technology and yes that tablet is compatible with AT&T's 3/4G but not with ours meaning with us you would only get 2G so at maximum you are looking at about 100 kbps on our network.

              As far as calling that would depend on the tablet, I am fairly sure that specific tablet does not support voice and so you would need to rely on some type of voip like skype or google voice neither of which will work only using 2G.

              In closing if you are going to be using a lot of data on the go and need to use voip services on your device AT&T is probably a better bet for that specific device.


              However let us know if you have any further questions we are still more than happy to answer what we can

                This is an unlocked quad-band GSM phone/tablet, so I'm pretty sure it does support voice.

                  Thank you so much for answering Keith. You explained quite a lot. I think I am going to see what happens when I try the T-Mobile sim card I ordered. I also ordered one from AT & T. I will post the results from both just in case the 7.7 is more capable than they let on...starting to feel like a poineer :-)


                  All the best,

                    Thank you very much for replying sga000!


                    I am quite the novice at this as you may have already gleaned from the contents of this thread. Anyway, as I mentioned above, I am going to try two different sim cards and see what happens. I'll post the results this week :-)


                    Thank you again,



                    • 7. Re: Unlocked  Samsung Galaxy Tab 7.7 WiFi+3G P6800 16GB and T-Mobile Sim Card?

                      Robert, I researched a little more, and the P6800 definitely can make voice calls.  There is a different model made specifically for Verizon, and that one does NOT allow voice calls.  And there is a WiFi only model, and obviously that does NOT make voice calls.  So either T-Mobile or AT&T sims should work for voice calls.  But as Keith said, AT&T will provide better data performance than T-Mobile (2G).  I look forward to hearing the results of your tests.

                        Hi sga000 and Keith!


                        Thank you both for your help with my device. In the end, it turns out that despite only going up to 2G for data, I have decided to go with T-Mobile! Below is my update (which I copied and pasted from my review on Amazon). Thanks again, and all the best!




                        Hi Everyone!


                        Well, I promised an update, so here goes:


                        My 7.7 arrived within four days of ordering, including a weekend...all the way from Hong Kong. Beautiful!


                        Hard to believe, but I am still waiting for AT&T to deliver the sim card I purchased directly from them for $5.00. Tomorrow will be a week since I ordered it. The whole process with AT&T was very difficult. They automatically want me to pay $35 to activate the line, and they will not allow pay as you go. You have to sign up with a monthly plan, no commitment. But still, you have to pay every month if you want the account to remain active. Didn't like the chat experience at all! At the end, they hit you with a 40 page agreement which made me feel like I was signing up for a commitment. Really bad way to run a company--it's just not clear cut. The rep finally said, "Look, when you get the card, call to activate it, and tell them you aren't paying for the activation." Wow! I am also going to tell them that if I can't pay as I go, meaning on the their pay be the day plan, with data package (which is ridiculously expensive, but mandatory) I am not activating with them and to hell with their 3G and 4G networks!


                        Now, why I am I so bold all of a sudden? Well the answer is T-mobile. I have to say, that in comparison with AT&T, they have great, great customer service. I spent quite a lot of time in their forums getting information by posting questions. They were very, very honest and even helped with a comparison between T-mobile and AT&T. It turns out that the 7.7 will work on both networks as a phone with no problem. It will work up to 3G for data on AT&T, but only up to 2G on T-mobile for data. T-mobile is in the process of working on their network and when it is complete it will be backwards compatible with the 7.7 up to 4G (of course the 7.7 tops out at 3G). They were very patient and helpful in terms of picking out my service plan. I opted for pay per day of use at $2; unlimited talk, text, and data, up to 2G speeds. When the network is ready to be compatible with the 7.7, the same pay per day for up to 3G will be $3 per day--if I choose that I want 3G. It will be up to me, I could still only pay $2 per day and stay with up to 2G. If I find that I am using the 7.7 all the time for phones calls, I can save about ten dollars per month or so by going on a monthly, no commitment plan. Also, there is no charge to activate the line.


                        Anyway, the T-mobile sim card arrived in two days, I called to activate, and there was a problem with the activation code. It took a few calls, but finally, someone just issued a new activation code while I waited. At first they wanted me to send back the sim card and wait to get a new one! Anyway, it just proves that if you stick to your guns it works out OK. I mean really, it wasn't my fault that their activation code didn't work! So, I am all set up, I make a call, and it works PERFECTLY. I did look a little funny holding up a 7+ inch tablet to my head, but that is OK. I have a blue tooth headset on order :-)


                        Later I tried to go online, and nothing happened. I contacted T-mobile customer service chat again, and we figured out that since the phone wasn't a T-mobile model, it would need to be set up. The agent asked me to call and ask for technical support, which I did. He had me up and running in five minutes. The speeds are just fine at 2G. I don't need to stream video or music, and I find web browsing to be fast enough at 2G. Anyway, it really doesn't matter that much, because the 7.7 can automatically switch to wifi when it is available. Since I am inside all the time, I can use the 7.7 for voice calls, and access the Internet from my wifi. I am very happy with this solution.


                        Oh, did I mention that I LOVE THIS DEVICE! I actually see it, and it is actually very, very intuitive in use. I am totally new to the android operating system, but I already have the 7.7 set up the way I like it, and it is very, very, cool!


                        I will let everyone know how the bluetooth headset works out. I also ordered a stylus (even though Samsung says not to--very weird since it seems that the screen on the Galaxy Note is the same as on the 7.7), and I will let you know if the stylus works out better than the various keyboards and trying to write with my finger tip...



                        Thanks everyone!

                          Great news, Robert!  Personally, I prefer T-Mobile to AT&T any day.  And I think your 7.7 may be the tablet I eventually get.  So thanks for your feedback!

                              I finally found the answer to my mistery.....I have a Samsung Tab 7.7 and am using a prepaid sim with the $3/day plan.  I haven't been able to get anything other than EDGE on data but contacted your customer service and technical support a few times.  No one has given me a straight answer of why its not getting 3/4G data connection.  And all the time I have been paying for $3/day expecting 4G service.  Now I understand the reason but I have wasted quite a bit money !!

                                Thanks for this information. I'm coming to the US from Australia with my Galaxy Tab 7.7(same setup as zenduder) in September and these comments confirmed what I've been trying to find out.

                                  Hi Keith,


                                  It's me again. I hope you are well!


                                  Quick question--do you have any idea if the upgrading to be backwards compatible with my 3G Samsung galaxy tab 7.7 p6800 has happened in NYC yet? If you don't know, can you suggest whom I should contact to try to find out?


                                  Thank you, thank you, thank you!


                                  All the best,
