From July 30 through Sept. 30, customers who sign up for T-Mobile’s Simple Choice plan can get four smartphone lines with unlimited voice and texting and up to 10 GB of LTE data, or 2.5 GB each, for $100 per month.
But the offer will only last until Jan. 2, 2016. After that date, customers will be reduced to 1 GB of data per line.
AT&T’s $160 Mobile Share plan, like T-Mobile, offers unlimited voice and 10 MB data, and lets customers can pay for a device via a separate monthly installment plan or bring their own device. However, AT&T does levy international roaming fees and overage charges and T-Mobile does not.
