T-Mobile's MetroPCS brand has quietly re-enabled its four lines for $100 promotion for an unspecified "limited time". The promo works with MetroPCS' $40/month unlimited plan. Two lines are $70 per month, three lines are $90 per month, and four lines are $100 per month. Plan prices include all taxes and fees, however MetroPCS stores typically charge an activation fee of between $15 and $25 per line.
Each line gets unlimited talk and messaging and 1 GB of high speed data. After the high speed data is used up, unlimited data throttled to 128 Kbps is available for the remainder of the plan month.
The promotion is only available at MetroPCS stores, not online and it applies to new GSM lines of service only. You can buy new phones or use your own compatible phones (any T-Mobile phone and most unlocked GSM phones from other carriers). Click here to find a MetroPCS store.
