AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The simplest no-credit-check route is a prepaid plan: you pay for the month in advance, so the carrier is not lending you anything. Postpaid contracts, where you are billed after use and often pay off a handset in instalments, are where carriers look at credit and may ask a newcomer for a deposit. The CFPB notes that a positive credit record helps with deposits on cell phones, which is why new arrivals without one meet them.
A US phone number is one of the first things you need after landing: employers, landlords, banks and two-factor login codes all expect one. Without a US credit file, though, the standard contract offered in a carrier's shop can come with a deposit, a credit refusal or a handset you cannot finance. The fix is to choose the plan type that matches where you are in your first year.
Prepaid and postpaid: the difference that matters
| Prepaid | Postpaid | |
|---|---|---|
| How you pay | Before the month starts | After the month, on a bill |
| Credit check | Not usually, because you are not given credit | Common, because the carrier extends credit until you pay |
| Deposit for newcomers | Not usually | Possible if you have no US credit file |
| Phone | Bring your own unlocked phone or buy one outright | Often financed over months, which is a loan |
| Stopping | Stop paying and the service lapses | Contract terms and any device balance apply |
Exact rules differ between carriers and change, so read the carrier's own terms for the plan you are considering. The pattern above is the general shape: no lending, no credit check; lending, credit check. The same logic explains why a carrier may run a check on a prepaid plan only when you finance a handset with it. For a first month in the country, many people start prepaid, wait until their address, SSN and bank account are settled, and then decide whether a contract is worth it.
Why carriers ask for deposits
A postpaid line is a small unsecured credit line. The carrier provides service for a month and trusts you to pay afterwards, and if a handset is financed the amount at risk is larger. With no US credit history, the carrier has no record to judge you by. The CFPB's credit booklet lists "paying deposits on utilities and cell phones" among the things a positive credit record helps with. In practice, a newcomer may be offered a postpaid line only with a deposit, a limit on the number of lines, or no handset financing. Utilities do something similar, explained in our guide to utility deposits.
Routes that avoid a credit check
- Prepaid with your own phone. If your phone from Nigeria is unlocked and works on US networks, a prepaid SIM or eSIM is often the quickest option. Check the carrier's compatibility tool before you buy.
- Prepaid with a phone bought outright. Paying for the handset in full removes the financing that triggers credit checks.
- Joining a family member's plan. A relative already in the US can add a line to their account. They carry the account and the credit relationship; agree in writing who pays what.
- Postpaid with a deposit. If you want a particular contract, ask what the deposit is, whether it earns anything, and when and how it is refunded.
Does a phone bill build US credit?
Usually not by itself. The CFPB's research on how people become credit visible notes that alternative data such as rent, cell phone or utility payments is typically excluded from traditional credit reports. The CFPB booklet adds that some companies let you have rent or cell phone payments reported to the credit reporting companies. So the accurate answer is: a phone bill does not count unless a service reports it, and even then a given lender's score may not use it.
The CFPB lists more reliable first steps, such as a secured card or a credit-builder loan. Our guide to building a US credit score from scratch covers them, and our rent reporting guide explains how alternative data is used. Late payment, on the other hand, can hurt: an unpaid postpaid bill passed to a collector can appear on your report.
Keeping your Nigerian number
If your Nigerian bank sends login and transfer codes to your Nigerian number, losing that line can lock you out of your account at the worst moment, so many people keep it alive alongside the US one. Read how to keep a Nigerian SIM active from the US before you let it lapse.
What to check first
- Is your current handset unlocked and compatible with the carrier?
- Does the plan require a credit check, and what happens if you have no US file?
- What ID does the carrier need in store, and is a Nigerian passport enough on its own?
- Is there a deposit, how much, and what are the refund conditions?
- Does the carrier report payments to credit bureaus at all? Ask; do not assume.
Where Pryme fits
Pryme does not sell US phone plans. Its Personal Assistant can remind you of renewal dates and prepare payments for you to approve, which helps if you run a prepaid US line and a Nigerian line at once; airtime top-ups on Nigerian networks can be paid in the app. See the Personal Assistant.
Questions people ask
Can I get a US phone plan with a Nigerian passport?
Carriers set their own ID rules, so ask whether a passport is enough. For postpaid, the carrier may also want a US address and will look at credit. Ask the carrier what it accepts.
Which phone plan does not check credit in the US?
Prepaid plans generally do not, because you pay in advance. Check the specific plan's terms.
Why is the carrier asking for a deposit?
Because a postpaid line is a form of credit and you have no US credit history for the carrier to rely on.
Will paying my phone bill improve my credit score?
Usually not on its own. Phone payments are typically excluded from traditional credit reports unless a reporting service adds them.
