Switching carriers used to mean a trip to a store, an awkward wait at the counter, and a new SIM card fumbled into place while a rep watched over your shoulder. With Infimobile, the entire process happens from your couch, using either a small physical SIM card or a fully digital eSIM, and most people are up and running the same day they sign up.
If you’re moving your iPhone to Infimobile, this guide walks you through everything from checking compatibility before you buy to activating your SIM or eSIM to confirming everything works correctly afterward. We’ll also cover how to keep your existing phone number without any gap in service, what to do if something doesn’t activate right away, and why now is a great time to switch, with two of Infimobile’s most popular annual plans currently on flash sale.
What Is Infimobile, and Why Switch?
Infimobile is a prepaid wireless provider for people who want dependable coverage without the premium pricing or long-term contracts attached to major carrier plans. Every plan runs on a nationwide network with access to 4G LTE and 5G speeds where available, giving you the same kind of broad coverage footprint you’d expect from a bigger-name carrier, just without the inflated monthly bill.
Because Infimobile is a bring-your-own-device service, you don’t need to buy a new phone to switch; your existing iPhone works as long as it’s unlocked and compatible, which covers most iPhones sold in the last several years. Wi-Fi Calling and Wi-Fi Texting come included as standard features rather than paid add-ons, and every plan includes unlimited nationwide talk and text regardless of which data tier you choose.
Before You Start: Check Compatibility and Coverage
Before ordering anything, confirm two things. First, make sure your iPhone is unlocked, or specifically unlocked from a carrier that allows it to work with other providers. A phone still locked to its original carrier won’t activate on Infimobile’s network. If you’re not sure of your phone’s lock status, your current carrier can typically confirm it over the phone or through their app, and unlocking is often free once you’ve paid off your original contract or installment plan.
Second, check coverage in your specific area using Infimobile’s coverage checker on its website, since confirming signal strength where you live and work ahead of time avoids any surprises after activation. This step matters even if you’re already familiar with the general network Infimobile runs on, since coverage can vary block by block in denser areas and mile by mile in rural ones.
Infimobile runs on a nationwide 4G/5G network and supports the vast majority of unlocked iPhones from recent years, including models that support eSIM. If you’re not sure whether your specific iPhone is eSIM-compatible, checking under Settings > Cellular for an Add eSIM option is a quick way to confirm before you decide which activation method to use. Generally speaking, iPhone XR, XS, and later models support eSIM, while several years’ worth of older iPhones only support a physical SIM.
Step 1: Choose Your Infimobile Plan
Every Infimobile activation starts with picking a plan, since your SIM or eSIM gets tied to whichever plan you select during setup. Infimobile currently offers a limited-time flash sale on two of its most popular annual options:
| 10GB Annual Plan | 10GB high-speed data/month | 12 months | $75 upfront | ~$6.25/month |
| 20GB Annual Plan | 20GB high-speed data/month | 12 months | $120 upfront | ~$10/month |
Both plans include unlimited nationwide talk and text, Wi-Fi Calling and Wi-Fi Texting, and access to Infimobile’s 4G/5G network, with reduced (not cut off) speeds after your monthly high-speed data is used. Since this is flash sale pricing for new activations, it’s worth selecting your plan and locking in the price before starting the rest of the setup process.
Physical SIM or eSIM: Which Should You Choose?
Both options connect you to the same Infimobile network and plans, so the choice comes down to convenience and your iPhone’s capabilities rather than any difference in service quality.
A physical SIM makes sense if you’d rather have a tangible backup card, you’re moving Infimobile service between multiple phones over time, or your specific iPhone model doesn’t support eSIM. The 3-in-1 kit format means you don’t need to guess which size you need in advance, since it includes standard, micro, and nano options in one card that punches out to fit your tray.
An eSIM makes sense if you want the fastest possible activation, since there’s no shipping wait involved at all. The moment you complete your purchase, the activation email with your QR code typically arrives within minutes. It’s also a convenient option if you’re setting up a second line alongside an existing physical SIM, since you won’t need a second SIM tray slot to do it.
If you’re genuinely unsure, eSIM is the more common recommendation for iPhone users specifically, given how consistently Apple has supported the technology since the iPhone XR and XS. That said, either method gets you onto the same network with the same plan benefits, so there’s no wrong choice here.
Step 2: Order Your SIM Kit or eSIM
Once you’ve chosen a plan, Infimobile lets you activate in one of two ways, and neither requires a store visit or an in-person appointment of any kind:
Physical SIM: Infimobile ships a 3-in-1 SIM card kit that fits standard, micro, and nano SIM trays, covering essentially every iPhone model. This is the right option if you’d rather have a physical card as backup or you’re not confident about eSIM compatibility on your device.
eSIM: After purchasing your plan online, you’ll receive an eSIM activation email containing a QR code and, in most cases, the activation details as text as well, in case scanning isn’t an option. This is the faster route, since there’s nothing to wait for in the mail; activation can start as soon as the email arrives.
Setting Up Infimobile with a Physical SIM
- Once your SIM kit arrives, power off your iPhone.
- Use the ejector tool (or a straightened paperclip) to open the SIM tray, and insert the appropriately sized card from your 3-in-1 kit.
- Power your iPhone back on.
- Visit Infimobile’s website and select Activate SIM Card.
- Choose the plan you purchased, and decide whether to keep your current phone number or get a new one.
- Log in to or create your Infimobile account, and follow the on-screen prompts to complete activation.
- Once activation is confirmed, restart your iPhone to make sure it fully registers on the network.
Setting Up Infimobile with an eSIM
- Purchase your plan through Infimobile’s website.
- Check your email for the eSIM activation message, which includes a QR code and backup activation details.
- On your iPhone, open Settings and tap Cellular.
- Tap Add eSIM, then select Use QR Code.
- Scan the QR code from Infimobile’s email, displayed on a second device, a computer screen, or a printed copy. If you’re viewing the email on the same iPhone, tap Enter Details Manually and input the SM-DP+ address and activation code exactly as shown.
- Follow the remaining on-screen prompts, labeling the line if asked (for example, “Personal” or “Infimobile”).
- Wait for the plan to finish installing; this typically takes just a couple of minutes.
- Confirm your number when prompted, and your iPhone will automatically activate the plan.
Keeping Your Current Phone Number
If you want to bring your existing number to Infimobile rather than starting fresh, select that option during activation and be ready to provide your current carrier account number along with a recent bill or account summary. This information lets Infimobile request the number transfer, or “port,” from your previous carrier.
Number ports typically complete within a few hours to a couple of business days. It’s a good idea to keep your old SIM active and avoid canceling your previous service until the port fully completes, since canceling too early can interrupt the transfer and put your number at risk of being lost entirely.
Confirming Everything Is Working
Once activation finishes, whether you used a physical SIM or an eSIM, take a minute to confirm everything is functioning correctly rather than assuming it’s done just because the setup screen said so:
- Place a test call to make sure voice service is active, ideally to another phone rather than a voicemail box, so you can confirm two-way audio quality as well.
- Send a test text message to confirm messaging is working, both to another mobile number and, if relevant, to a group thread you use regularly.
- Check your data connection by opening a browser or app that requires the internet, and try it both on Wi-Fi and with Wi-Fi turned off to confirm cellular data specifically is active.
- Turn on Wi-Fi Calling, found under Settings > Cellular > Wi-Fi Calling, so you have a backup connection method in weak-signal areas from day one.
- Restart your iPhone if anything seems slow to activate, since this often speeds up the network registering your new line and can resolve minor first-day glitches.
If everything checks out, you’re fully set up and ready to go. If you ported an existing number, it’s also worth texting or calling a friend to confirm your name and number are displaying correctly on their end, since caller ID information can occasionally take slightly longer to update across networks than the line itself.
Troubleshooting Common Setup Issues
QR code won’t scan: Make sure you’re scanning from a separate screen or a printed copy, since scanning the code on the same device you’re activating won’t work. Use the manual entry option instead, and double-check the SM-DP+ address and activation code for typos, since these long strings are easy to mistype.
No signal after activation: Restart your iPhone and confirm the correct line is set as your default for cellular data under Settings > Cellular. If you’re using dual SIM with an existing line, make sure Infimobile’s line hasn’t been accidentally left inactive.
Activation seems stuck: Give it a few extra minutes, since network registration can occasionally take longer than expected. If it still hasn’t completed after 15 to 20 minutes, contact Infimobile support to confirm the activation went through correctly on their end.
Old eSIM profiles causing conflicts: If you’ve previously used eSIM with another carrier, remove old or unused profiles under Settings > Cellular before installing Infimobile’s eSIM, since leftover profiles can sometimes interfere with new activations.
Number port stuck or delayed: If you selected the option to keep your existing number and it hasn’t transferred within a couple of business days, double-check that the account number and billing information you provided match your previous carrier’s records exactly, since even small mismatches can hold up the transfer. Keep your old SIM active during this window, and contact Infimobile support if the delay stretches beyond 48 hours.
Wi-Fi Calling won’t turn on right after activation: This setting sometimes takes a little longer than voice and data to fully register on a brand-new line. Give it 30 minutes to an hour after activation completes, then check Settings > Cellular > Wi-Fi Calling again before assuming there’s a deeper problem.
Why Now Is a Good Time to Switch
Beyond the setup process itself, timing matters here. Infimobile’s flash sale on its 10GB and 20GB annual plans means new activations can lock in a full year of nationwide 4G/5G coverage, unlimited talk and text, and included Wi-Fi Calling for a single upfront payment well below typical monthly carrier costs. This pricing is for new activations only and won’t be available indefinitely, so if you’ve been meaning to switch your iPhone over, completing the setup now secures the lower rate for the full year ahead. Terms and eligibility apply, and full plan details are available on Infimobile’s website.
Quick Tips for a Smooth Setup
- Confirm your iPhone is unlocked before ordering, since a locked device can’t activate on Infimobile’s network.
- Check coverage in your specific area ahead of time using Infimobile’s online coverage checker.
- Keep your old SIM active until a number port fully completes, to avoid any interruption to your existing service.
- Save your eSIM QR code and activation details somewhere secure, in case you ever need to reinstall the profile after a factory reset.
- Update your iPhone’s software before activating, since outdated iOS versions can occasionally interfere with eSIM installation.
Frequently Asked Questions
Yes. Your iPhone needs to be unlocked, or unlocked from a carrier that permits switching, before it can activate with Infimobile or any other provider. If you’re unsure of your phone’s lock status, your current carrier can confirm it for you, and unlocking is typically free once any installment plan or contract term tied to the device has been fulfilled.
Yes. Infimobile supports both options: a 3-in-1 physical SIM kit that fits any tray size, or a digital eSIM activated through a QR code sent by email after purchase. Which one you choose comes down to personal preference and whether your iPhone supports eSIM.
For most people, the entire process takes somewhere between two and ten minutes from scanning the QR code to being fully connected, and eSIM customers are typically active on the network the same day they sign up. Physical SIM activation is just as fast once the card arrives, though you’ll need to factor in shipping time beforehand, which is the main reason many people choose eSIM when they want to get connected immediately.
No, as long as you select the option to keep your number during activation and provide your current account details for porting. Keeping your old SIM active until the port completes is the safest way to avoid any interruption.
Try scanning it from a different screen than the one you’re activating, since scanning the same device’s screen doesn’t work. If scanning still fails, use the manual entry option in your iPhone’s cellular settings and carefully enter the SM-DP+ address and activation code exactly as provided in your confirmation email.
Final Thoughts
Setting up Infimobile on an iPhone is designed to be simple enough to do entirely on your own, whether you go with a physical SIM or an eSIM. Check your phone’s compatibility, pick your plan, activate online, and confirm your connection. Most people are fully set up within minutes rather than hours, and porting an existing number adds only a short waiting period on top of that.
With Infimobile’s 10GB and 20GB annual plans currently available at flash-sale pricing, there’s real value in completing that setup sooner rather than later. Visit Infimobile online to check your iPhone’s compatibility, lock in your plan, and get connected before the sale ends.
