Sony Xperia SP for goPhone data plan


Sony Xperia SP for goPhone data plan

I will visit US in August and would like to buy a SIM card for the $2/day plan. I need voice and data for google maps navigation. I will bring my Xperia SP with me, mainly in NYC and DC. But I don't know if the SP is compatible with AT&T 3G/4G network or not. The network spec of my SP is:


4G LTE 2100/1800/850/2600/900/800 MHz

UMTS/HSPA+ 850/900/2100 MHz

GSM/GPRS/EDGE 850/900/1800/1900 MHz


Can someone tell me if the SP can us AT&T 3G/4G network?

Re: Sony Xperia SP for goPhone data plan

Yes, it is compatible. If it is unlocked, you can use an at&t SIM without problems.
I have Sony unlocked mobiles, and do not have problems others have with branded (at&t) Mobiles.
Good luck!!

Re: Sony Xperia SP for goPhone data plan

thanks for the reply. do you know which band does AT&T use for their LTE and 3G data? I ask because my SP was bought in Hong KOng, not US. It is not locked to any carrier, but I am afraid the bands AT&T uses is not compatible with overseas phones.

Re: Sony Xperia SP for goPhone data plan

Hi, I am also looking into this phone right now, the phone has difference models which support different radio frequencies:


2G Network GSM 850 / 900 / 1800 / 1900 - all versions

3G Network

HSDPA 850 / 900 / 2100 - C5303  

HSDPA 850 / 900 / 1700 / 1900 / 2100 - C5302
HSDPA 850 / 900 / 1900 / 2100 - C5306

4G Network

LTE 800 / 850 / 900 / 1800 / 2100 / 2600 - C5303  

LTE 850 / 1700 / 1900 / 2100 - C5306

AT&T's frequency is as follows, I will test it out once I have the phone, I ordered the C5306 model. I will test it out on both AT&T and T-Mobile too.

Frequencies used on the AT&T Network






700 MHz Block B 17 LTE 4G

1700/2100 MHz AWS 4 LTE 4G

I don't believe you'll be able to use the C5306 with AT&T LTE.


AT&T tech support and I have tried for 3 days, and no go.  Not only can AT*T not apply an LTE compatible data plan to the IMEI, but it seems like one of the frequencies the C5306 uses for LTE is not the one AT*T uses for LTE.


Also, the phone will not work with an AT*T 3G microcell.  The microcell will not accept it as a device to connect to.
