Switching deals come in four shapes. Device credits or trade-in value if you hand over an old phone. Sign-up credits, usually a lump sum spread over your first months. Bonus data or a temporary rate discount. And the one most people never collect: a retention discount from the carrier you are leaving, commonly $10 to $30 a month if you call before you port. All four are real. All four are designed so the 12- to 24-month total costs more than the month-one number suggests.
Three checks before you accept anything. First: how long does the discounted rate last? A rate that expires after 12 months means the real price is the post-deal price - do the math on that one. Second: what is bundled in? Device financing, auto-renewing insurance, and add-ons are where the deal quietly gets expensive; the typical big-three postpaid bill of $70 to $110 per line is mostly these things. Third: what happens if you leave early? Early termination fees and device buyouts decide your exit price. Total the deal across its full term, not the first bill.
For most people the best switching deal is not a deal at all. Skip the postpaid bundle entirely and move to a prepaid plan on the same towers: $25 to $40 per line, same phone, no credit check, no contract, cancel anytime. If you are paying the typical $70 to $110, that is a saving of $45 to $70 per line per month with zero fine print - $540 to $840 per line per year. No trade-in required, nothing to return, no rate that expires. Compare that against any advertised switching deal before you take it.
Before you port anywhere, call the carrier you are leaving and ask for a retention offer. $10 to $30 a month is the usual range, and it costs one phone call. Now compare: if the discounted bill is still above a plan in the $25 to $85 range, staying costs you that difference every month - the retention offer is a floor, not a destination. If the discounted bill does land below a comparable switch, staying a year and re-evaluating is a legitimate play. Either way, you now have the number in writing.
