im on a GS3 AT&T unlimited data grandfather... on LTE with unlimited grandfather you can use up to 5GB before you get throttled to super fast EDGE speeds

..you get get a free text from AT&T saying
"blah blah too much data this month reaching 4.6GB use wifi around you blah blah to reduce data speeds" .. so my friend has a i5 on AT&T and i wanted to do a experiment and see if it will still get low speed ...i cut my micro sim to nano sim and slapped it on the i5 and behold

throttling still takes affect not a surprise...same speeds less then 1mb down and up on both devices.... i got hit by throttling on my iphone 4 before on 3G and it was not as bad as on LTE..on 3G throttled its not constant under 1MB down/up.. sometimes i get 3/5+MB down and up on 3G throttling... seems like AT&T has it program were its under 1MB down/up 95% of the time till your new cycle starts..light web surfing is fine/pandora works fine/twitter is working but when loading pics takes a bit due to fast edge speed /youtube netflix/stream video you have to wait for your cycle to re new it takes long and lags/buffs no point...this is in my location in San Diego so place may vary ..plus i get close to 5GB a month anyways.. i had 5 days till my new cycle starts and i pushed my data over 5GB to see if i get better speeds on LTE compare to 3G when throttled.. i guess 3G throttled gets better speeds compare to LTE throttled..funny thing is that still says LTE on the status bar when its running at EDGE speeds..DAM you AT&T greedy money hungry company

yes i tried messing with the APN network to trick it to run HSAP+ an still edge speeds..AT&T wants people to cough out unlimited data for more $$$ they tell use use our tiered plan so you wont get throttled down but you will pay extra 10$ if you go over you DATA use.. yes i use wifi at work and home this was a test and its not fun begin throttled

well enjoy you new iphone 5 everyone baby it keep it clean and watch you data use..youtube is a big data killer specially when HD is on..LTE is nice but now you pay the price...the LTE speeds will spoil you
now i have a ghetto mod sim for my GS3..need to get a new one

its all taped up
