Yesterday I posted a piece titled "Straight Talk to Offer Unlimited LTE 4G Data, Talk and Messaging On AT&T for $45/month!" about a rather nice new Android phone, the LG Optimus 2X, that's coming to Straight Talk. I reported that the phone supported LTE 4G and would use the AT&T network, as did several other mobile tech sites.
It turns out that I was almost certainly wrong. New information all but confirms that the Optimus 2X doesn't support LTE and uses the T-Mobile network. What happened was that Straight Talk posted this on their Facebook Wall:
Reserve your 4G LG® Optimus 2X™ UNLIMITED GSM phone at http://reserve.straighttalkandroid.com.When you went to http://reserve.straighttalkandroid.com you saw this:
Note that the bottom left hand corner it says "4G LTE Mobile Broadband". There are only two US carriers with LTE networks currently; AT&T and Verizon. So which is it? That's easy, the Straight Talk site has an interactive tutorial for the Optimus 2X that shows its model number as LG 95G. All Straight Talk models ending in "G" are use GSM as their voice technology. Verizon uses CDMA not GSM and Straight Talk CDMA phones have a model number ending in "C". So the Optimus 2x can't be on Verizion. But it supports LTE which means it can only be on AT&T. At least that's what a of reporters thought, including me. Unfortunately, it's also probably completely wrong.
Late yesterday, a Howard Forums member discovered a 3 month old thread on XDA-Developers where "exonic" posted that they were given a GSM Android phone by someone who works for Straight Talk.
The phone didn't have any carrier branding but it looked just the T-Mobile G2X. The "About Phone" section of the Android Settings menu showed its model number as LG L95G which we now know as the model number of the Straight Talk Optimus 2X.
So three months ago this person apparently had apparently had a pre-release Straight Talk Optimus 2X. The phone was SIM locked and neither T-Mobile or AT&T SIMs worked, which is typical for Straight Talk phones. There was a label under the battery (image here) with the phone's FCC ID: BEJP999DW. If you search for that with Google you can find the documents that LG submitted to the FCC in order to get the phone approved. The document labeled Test Report lists the phone's radio technogies and frequencies as 850 and 1900 Mhz GSM (2G) and 1700/2100 Mhz (aka AWS) WCDMA/HSPA (3G - 4G). LTE is not mentioned. In the US only T-Mobile uses 1700/2100 MHz for high speed data. So if exonic's phone is a Straight Talk Optimus 2X, and it appears to to be, then Straight Talk's claim that the phone supports LTE is false. Also my assumption, based on the LTE claim, that it uses AT&T is wrong. The Optimus 2X appears to use T_Mobile.
In addition, overnight the reserve.straighttalkandroid.com page changed. There is no longer any mention of the Optimus 2X. In it's place is a page promoting the LG Optimus Q, which has been available for some time and does not need to be "reserved". Update: after another 24 hours, the Optimus 2X "Reserve" page has reappeared. The only change is the removal of "LTE" from the phrase "4G LTE Mobile Broadband.
It seems that the reference to LTE was a mistake. Is Straight Talk guilty of sneaky guerrilla marketing or just incompetence? I don't know but it will be a long time before I take anything they say at face value again.
Update: 7-Mar-2012 PhoneNews.com is reporting that the LG Optimus 2X for Straight Talk and Net10 has been canceled. This has not been confirmed by America Movil.
