It means that Gmail app is downloaded but not able to connect to your Gmail account. Is this correct? If yes, then check "Permission" settings. If ok then try to use internet profile (just like email client) instead of wap profile. May be service provider is responsible for this because I was using internet profile with Gmail app on Samsung E200 on ZoNG SIM few months ago. But now, Gmail app is working fine with wap profile using same network provider on C5212. The new Gmail version 2.0.6 is working fine on C5212. No need to change memory setting.

      Usman Afzal, 04 Oct 2009There should be no problem when install Gmail via WAP brows... moreI have an active GPRS connection and I can use other applications such as Google Maps and ngpay. The problem is only with Gmail application. I have deleted and reinstalled the same a couple of times. But it is not working. I tried to get help from google mobile help forum. I tried to download the verisign certificate into my mobile. The file is being saved in the Games folder. As Google Maps is working fine I believe that the problem will not be with the verisign certificate. I wish to know if the problem will be with the memory allocation. I have already installed other programs without increasing the memory. will increasing the memory help?

First of all, make sure that you have active GPRS connection. Go to m.gmail.com and open "Get faster Gmail" link. You will see "Install Now" link. Click to this link. Another page will open with text line "To begin the download, please select this link". Click on "this link". This will install the Gmail software on your C5212 mobile. Current version is 2.0.6 having 257KB size.

Thank you so much. I was not getting GPRS and other apps on my mobile. After making the EDGE/EGPRS changes as said by you I can access Apps like ngpay, Google Maps, Opera mini and some general browsing. I am not able to access Gmail mobile app yet. I have tried to delete and re-download it but when i try to access the program it shows error. When I download the program it shows that Google cannot automatically detect the model of the handset. Hence I download the general version. It cannot be used on c5212. Please help.

So, your mobile net is not working due to some other reasons. Please manually check "WAP browser" profile settings. And unfortunately, you can't increase 4MB JAVA Games folder size. You must delete some games to install new games/ softwares. You can delete Samsung pre-installed official games which are all useless. I have installed some new games/ softwares like Opera Mini 1.27 mod, Face Warp (from SE, have similar options as Warp feature of Image Editor of C5212), File Hide, Opera Mini 4.2, Opera Mini 5 beta, Agassi Tennis, KD Player 0.9.6, DynamoKid, Chess, Gmail 2.0.6, Google Maps 2.3.2, MobiCast 2.4, File Explorer 1.0, UC WEB6.0.0, Azan etc.

                        Subash Patel, 19 Sep 2009Hello, I was annoyed with changing SIM cards in mobile phon... moreI am afraid that you have got a faulty set or with an older firmware because I don't have any problem that you are facing.

                        (a) I can say that C5212 has two transceivers with two IMEI numbers because when I am talking to someone on SIM1 and another person is calling me on SIM2, then I gets a pop-up message on screen with other person's name (if his name is saved on my phonebook) or his phone number and with options to "Accept" or "Reject" the phone call.

                        (b) I don't have any hanging problem after switch-on and off operation.

                        (c) You are correct about maximum JAR file size limit which is 400 KB maximum BUT you can increase this limit to even 2 MB in few seconds. I have successfully installed 1.4 MB sized software on my C5212 directly from memory card. Just follow this simple step:
                        Enter this code in standby mode: *#52828378#
                        You will see "JAVA Test Menu" screen. Select option # 6 which is "OTA Test". Here you can see "Maximum JAR size (KB) which is 400 KB by default. Just enter your own value like 2048 KB. Press "Save" and exit from it. Now you can install JAR file of upto 2 MB size. Just make sure that you have placed both JAR/ JAD files in the SAME folder. Then select JAD file and select "Install" option.

                        (d) Both slots (SIM1 and SIM2) supports EDGE class 10. Make sure that your both SIMs are EDGE supported. I have checked your claim and found it wrong! I have two SIMs, one is EDGE enabled (ZoNG on SIM1) and other one is GPRS enabled (JAZZ on SIM2). I gets "E" icon when using internet from ZoNG and gets "G" icon when using internet from JAZZ. To check your claim, I opened the casing of mobile and interchanged the SIMs. So, after that I had ZoNG as SIM2 and JAZZ as SIM1 and I got "E" icon again when using ZoNG as SIM2.

                        Make sure that both slots (SIM1 and SIM2) are set with EDGE class 10 support. To check this, follow this simple step:
                        Enter this code in standby mode: *#4777*8665#
                        You will see "GPRS Tool" menu screen. Select option # 4 which is EGPRS MultiSClass. Now again select optio # 4 which is MultiSClass 10 (means EDGE class 10). Press "Back" and select option # 6 which is "GPRS Setting". Here you can see two options (EGPRS mode and GPRS mode). Just select EGPRS mode. This will save your setting. Now select your other SIM setting by pressing left or right navigation center key and repeat above procedure for SIM2. Now you have set your both slots (SIM1 and SIM2) at EDGE class 10.

                        (e) It uses same charger of my old Samsung J150. So, I am very satisfied with it.

                          last week I bought a samsung c5212 dual sim. I'm not satisfied on that product. the serious draw back is on its hearing speakers quality. Its very poor as compared to nokia models. Even a bese nokia model occurs good hearing speakers. while conversing we feel this.The company offers upto 13 hrs talk time. Its wrong. We will get only upto 3 hrs only. if anybody has same experience pls share with me

                            Hello, I was annoyed with changing SIM cards in mobile phone, and went to C5212 some three weeks ago. I did lot of research on D780 and C5212, along with lot of Chinese sets and found this was better one. My objective was to use both SIM at same time for data and voice.

                            I have been satisfied with overall performance of this phone. But I have seen some drawbacks as below:

                            1. I paid for the brandname. Else this phone also has a single TRX, and hence when one line is on call, other will fail (person who called on that network will recieve not-reachable or switched off). I preferred both SIM's to be active, and switch calls if I need. Timeslot management should not be that difficult ofcourse.

                            2. Whenever I switch off and switch on, the mobile hangs ! displaying "SIM Initialising". I called customer support and they informed to get a software upgrade. 3 weeks and a upgrade already !

                            3. Application support is pathetic. They support signed Java applications upto 400KB only ! This is unacceptable for someone like me who use Google maps to find directions many a times. I am not able to use it now :(

                            4. EDGE available is class 10 in master sim only (slot 1) for downlink. For its uplink, and on slot 2 its GPRS. Not sure what challenges are there to support EDGE on both.

                            5. Lacks universal charger slot which is supposed to come from 2012 (mini USB). I saw that it doesnt allow even Samsung E840 charger which my wife uses. Now I am forced to carry it everywhere.

                            Overall, I found that this phone is not worth the price I paid. I have used Nokia and Motorola brands before, and find them value for the money I paid. Especially Motorola... I miss the crystal talk I had one my lost L9 :(

Just go to Menu/ Settings/ Phone profiles. Now select "Normal" profile and go to "Options/ Edit". Now change "Call alert type" to "Vibration and melody" by just pressing center OK key. Now press "Save".
                              You can use both SIMs at the same time for messages, internet, phone calls without restarting your mobile. I am using C5212 with two SIMs in it for messages, phone calls, internet and I use "SIM selection" button to switch over to other SIM, no matter which SIM is set as default.
                              Battery duration is excellent for me (more than 2 days or approx 50 hours) although I also use Opera Mini for approx 1 hour, FM radio/ recording for approx 30 minutes, MP3 player for approx 30 minutes, 1 or 2 phone calls, 4 or 5 text messages, email checking on daily basis. I have been used many Samsung mobiles before like X700, D500, D600, E200, E250, D900, J150 and I can tell you that C5212 has better battery backup time than above mentioned Samsung mobiles.
