Straight Talk – More Phone Options Including Verizon, AT&T & T-Mobile Services

Straight Talk continues to expand their offering of not only cell phones, but also the carriers they are using. Besides using the Verizon network for their CDMA services, the company has added GSM networks from AT&T and also T-Mobile, depending on the service quality in your area. Last night I contacted Straight Talk support and asked for clarification on the networks they are currently using. I received this reply:

We would like to inform you that Straight Talk is using the CDMA and GSM technologies. The Straight Talk phones that are under the CDMA network do not have a SIM Card. These phones are powered by Verizon. However, the phones under the GSM network have a SIM Card and they are powered by AT&T or T-Mobile (depends on the best working carrier on your area).

Please be advised that the Nokia E71 and Nokia 6790 are powered by AT&T only. Thank you for your inquiry.

One of the questions that has been asked by readers is if you can take a non Straight Talk phone [GSM only since CDMA phones do not have Sim cards] and use the phone with the Straight Talk service. Some have responded that they have had success using a ST SIM card in another unlocked phone and have indicated it worked for them.

However, the general consensus is though the phone may work, when you leave the area, the phone may not work for roaming.

My advice is this. Stick with a Straight Talk enabled phone for the best results. But if you have a GSM phone that you just have to have, you can try using the ST SIM but results are going to vary widely, depending on the make and model of the phone.

There is a lot of misinformation about ST phones. One reader noted the Nokia E71 works on both Verizon and AT&T which is false.

Comments welcome.
