I just read that it means it did NOT go through.. Now I need to know if it is a issue with my phone or just the other person's phone was turned off or something on their end. ----------------------------------------------- Back again...I been reading posts and researching, but so far nothing is working. I do not want to reset the phone since I had to unlock it and afraid that this will disable my unlocked phone. Anyone have any suggestions. I have accessed the internet with it and added some apps, could something have happened? I noticed that there is no inbox or outbox for messages at the top where they are suppose to be when opening up messages. Where did they go and can I install something to fix this. I did copy and paste my 2GIG memory chip to a 4GIG memory chip for more room and then put it in the phone. Any issues with that?
---------------------------------------------------------------------- Back again and I just read this post, credit goes to GORDOG, Thanks to you and the guy who you got it from. This helped me very much on major part of setting up my phone after being unlocked from Movistar to use with Telcel. I will post what you have to help others. I still am unable to send sms messages successfully
...................... Always include: Device: All Android phones Carrier: TELCEL (Mexico) Country / Language: Mexico / Spanish and English OS / Browser / build number (if applicable): Android Eclair, Froyo I have been receiving numerous requests and questions as to how to configure an Android phone to be used with México's TELCEL carrier under their 3G network. I wrote about this almost one year ago, nevertheless the information is still current and valid for any Android phone, using Eclair, Froyo (and I dare to guess is also valid with Gingerbread). So, here again I report that article I wrote, I made some minor corrections but bear in mind the info is correct, valid and thoroughly tested by many. Enjoy and do not hesitate to contact me if there are any questions: On April 2010 I bought my Nexus One in the U.S. now, almost 1 year after, I still have it and use it daily. I use my phone mostly with the carrier TELCEL in Mexico. For that I needed to find out how to configure the phone to be able to: Use 3G network (with all its features such as high speed) and be able to send MMS (multimedia messages). Here is the whole setup for all you Mexican users with an Android based device: For an Android device to work in Mexico you need to comply with several steps: a) First: if you bought your phone in the USA your device MUST be unlocked, that means you should be able to change the SIM card for that of another carrier (cell company) and the phone should not complain. If it works, then you are OK. If your got your phone with the carrier (TELCEL), it's probably already configured and you do not have to worry about this...even tough the phone is probably locked to TELCEL (ie, you won't be able to use it on another carrier / cell phone company...unless unlocked). b) Your device must have and support the frequencies used in Mexico. There are two things to consider about frequencies: GSM frequencies AND 3G frequencies. In México, the standard GSM frequency band for 2G (that is Second Generation: 2G) services is 1900 Mhz. If a phone supports GSM 1900, it will work with voice calls on the cellular networks in Mexico, (or slow data using EDGE/GPRS), using GSM technology; the name for that is ROAMING. c) Regarding 3G frequencies, Mexico's TELCEL uses the UMTS 850 Mhz frequency band. You need your Android phone to have THAT specific frequency to work with Telcel's 3G. If you bought your phone in the USA and it was made to work with AT&T 3G network chances are you got the right phone for TELCEL 3G in Mexico. 3G speeds and features are completely independent of GSM voice calls and/or EDGE/GPRS slow data already working. Again, you need to get a phone that has the 850 Frequencies, otherwise, at the moment of this writing it won't work on TELCEL's 3G network. These frequencies are valid at the time of writing this (February 2011), there are plans to open other band and frequencies to offer data and voice services...but that is another story. d) You need to configure your Android phone (AT&T 850 Mhz frequencies version, remember) to include the APN, you do this as follows: Remember, this if for Mexico's TELCEL which is the one I use, nevertheless, for other operators the settings should be pretty similar, of course the values for the some APN fields will change. Now, the good stuff: TELCEL's 3G configuration: In your Android phone, Get into: Settings -> Wireless and Networks settings -> Mobile Networks -> Access Point Names (APN) Then Create one NEW access point and give it a name, I used: "Internet 3G" Fill in the data as follows: APN: internet.itelcel.com <-------- This is internet.itelcel.com itelcel has an initial "i" Username: webgprs Password: webgprs2002 APN type: default <-------- Type the word "default" in lowercase and don't put in the quotes Leave all the rest fields with their default values. Continue on to configure MMS (multimedia messages) APN or, if you just want 3G connectivity for now Reboot / restart your phone and you should immediately be connected to the Telcel's 3G network. Now, for MMS (multimedia messages) setup, do the following: Again, in your Android phone, get into: Settings -> Wireless and Network settings -> Access Point Names (APN) Then Create one NEW access point and give it a name, I used: "Mensajes Multimedia" Fill in the data as follows: APN: mms.itelcel.com <-----Again with an initial "i": itelcel Username: mmsgprs Password: mmsgprs2003 Select the MMSC field and type the following string (no quotes): "http://mms.itelcel.com/servlets/mms" PROXY MMS: 126.96.36.199 MMS Port: 8080 MCC should already be as: 334 MNC should already be as: 020 APN type: mms Leave all the rest fields with their default values, even if they are empty or null Reboot your phone and you should immediately be connected to TELCEL's 3G network. You will see the "3G" icon on the top right side of your screen. You should also be able to send multimedia messages (photos, for instance). Hope this information helps. If you need further information on how to connect your Android phone to Mexico's TELCEL cellular phone network, let me know. Kind regards from Mexico City Some important highlights from the mails I received : If you haven't please take this into account : 1) Yes; I can confirm the domain names referenced are "itelcel.com" with an initial "i". 2) For 3G setup: On 'APN type" you need to type the word "default" (no quotes tough). This tell the phone to use this APN by "default" when trying to connect to Telcel's 3G network. Hope this info helps. Thanks to all who sent their comments to me.
