When you’re planning an independent trip to the US, you probably think about Google Maps, Uber, and finding good places to eat. But have you ever considered that your “phone number” might be the easiest thing to overlook on the whole trip?
Picture this: you’re waiting for a table at a popular restaurant in New York, and the host asks for your cell number so they can text you when your table is ready. That’s when you realize the travel eSIM you bought is data-only, with no US +1 phone number. So can you still get on the waitlist? Will texts reach your Taiwan number? And does Uber really require a US number too?
Honestly, not everyone traveling independently in the US needs a +1 US number. If your Uber account is already set up and you mostly rely on maps and internet-based apps, a data-only eSIM plus keeping your Taiwan number active will usually cover a lot of what you need. But if you’ll be using US restaurants’ text-based waitlists a lot, need local businesses to call you back, or want to receive US calls and SMS, an eSIM that clearly includes a +1 number, calls, and texts gives you more flexibility.
1. Do You Really Need a Phone Number for a US Trip? Start With This Table
| Travel situation | Can a data-only eSIM usually handle it? | When should you consider a +1 number? |
|---|---|---|
| Google Maps, websites, social media | Yes | Usually not needed |
| LINE and WhatsApp internet calls | Yes, as long as both sides use the same service | When the other person can only take regular phone calls |
| Booking restaurants on OpenTable | In many cases, you can manage it through the website/app and email | When the restaurant requires phone confirmation or SMS |
| Yelp Waitlist | You can view some info online, but notifications rely on SMS | When you need to reliably receive waitlist texts from US restaurants |
| Ordering an Uber | If your account already exists and is verified, most everyday use just needs data | When signing up, changing your number, or re-verifying by SMS |
| Taiwanese bank OTPs | Depends on your original Taiwan number or your bank’s app | A US +1 number can’t simply replace your Taiwan number |
| Local businesses calling you back | Data-only plans don’t come with a regular voice number | When businesses often need to call you |
The key thing to understand here: having internet access, having a phone number, and being able to receive a specific platform’s verification texts are three different things.
2. How Do You Book US Restaurants on OpenTable? Do You Need a +1 Number?
OpenTable is one of the most common restaurant reservation platforms in the US. You can check availability, dates, and party size, and manage your bookings.
How to Make Your First Reservation
- Open the OpenTable website or app and search by city, restaurant, and date.
- Choose your party size and an available time, and check the booking conditions.
- Enter your contact details as prompted and complete any required confirmation.
- Save the confirmation email or the booking record in the app.
- At the restaurant, give the host the name on the booking (“Reservation under ”).
Some restaurants may ask for credit card details to guarantee the booking, or charge a fee for no-shows or late cancellations. Entering a credit card doesn’t mean you’ll be charged for the meal right away on every booking, so read each restaurant’s cancellation and deposit policy.
What If You Don’t Have a US Number?
According to OpenTable, the platform may send booking confirmations, reminders, and change notices by email, text, or app push notification, and some restaurants support direct messaging in the app. That doesn’t mean every restaurant requires you to successfully receive a US SMS before you can book.
So you can start by using your original Taiwan phone number and a working email address and follow the on-screen prompts to complete the booking. If the form won’t accept an international number, or the restaurant only accepts local US cell numbers, contact the restaurant directly and ask about alternatives. Don’t just enter a stranger’s number.
If a popular restaurant is fully booked, some OpenTable features let you set an availability alert (Notify Me) that reminds you via app push notification. But an alert doesn’t book the table for you automatically; once you get it, you still have to go through the process and grab the opening.
3. What Is Yelp Waitlist, and Why Do Restaurants Ask for Your Cell Number?
This is a situation that deserves even more attention than OpenTable.
Some US restaurants don’t take traditional reservations and instead use Yelp Waitlist to manage walk-in waits.
You might hear the host say, “I can put you on the list, and we’ll text you when your table is ready.”
Yelp states clearly that once you join the waitlist, the system sends a confirmation SMS, and another text when your table is ready. You can also check your waitlist status in the app, but you shouldn’t assume the app alone guarantees you’ll receive every notification.
How to Use Yelp Waitlist
- Search for the restaurant on Yelp and see whether it supports Waitlist.
- If online waitlisting is open, tap Join Waitlist.
- Enter your name, party size, and contact details.
- Keep an eye on your text messages, your waitlist status in the app, and your check-in time.
- When your table is ready, head back within the time limit following the restaurant’s instructions.
If you only have a Taiwan +886 number, will the texts reach you? Not necessarily. Whether international texts get through depends on the waitlist system, the SMS provider, and carrier routing, so there’s no guarantee it will work.
In that case, you can just ask the host:
Could you call my name instead of texting me?
Or ask whether you can leave an email address or simply wait on-site. Some restaurants are happy to accommodate, while others have to stick to their system. It ultimately comes down to each restaurant’s policy.
4. Do You Need SMS Verification Before Using Uber in the US?
Uber is used everywhere in the US, especially for airport transfers, getting back to your hotel late at night, or reaching places that public transit doesn’t serve well.
Signing up for Uber, changing your phone number, or triggering an account security check may require text verification. Uber also notes that carriers may block some short code SMS messages, which can stop verification codes from coming through.
But that doesn’t mean you need to receive a new US text every time you open the app or take a ride.
4 Things to Do Before You Leave
- Download Uber while you’re still in Taiwan, and sign up and verify with a number that reliably receives texts.
- Add a working payment method and make sure you can log in without problems.
- Save your account details and confirm that you receive email and app notifications.
- Once you land in the US, use your travel eSIM’s mobile data. Don’t rush to change the phone number linked to Uber just because you switched data plans.
If you reinstall the app in the US, log out and back in, or change your account details, you may still face extra verification, so make sure your originally linked number is usable.
5. US OTPs and Taiwanese Bank OTPs Are Not the Same Thing
A lot of people see “this US eSIM can receive texts” and assume they can switch their Taiwanese bank verification codes to a US +1 number too.
That’s not correct.
If your Taiwanese credit card or bank account is linked to a +886 mobile number, bank SMS messages will usually go to that Taiwan number, not the US number you just bought.
So the most practical setup is:
- Travel eSIM: handles your internet in the US.
- Your original Taiwan number: depending on what your carrier and bank support, keeps open the option of receiving Taiwanese OTPs.
- US +1 number: if your plan includes one, use it for restaurants and businesses that need a local number, and for local calls or SMS.
Keep in mind that receiving texts on your Taiwan number abroad doesn’t guarantee every bank OTP will come through, and voice calls, sending SMS, or data roaming may cost extra. Check with your home carrier first.
If your bank offers app push verification or another official verification method, make sure it’s enabled before you leave for extra peace of mind.
6. Native eSIM vs. Data-Only eSIM vs. eSIM With a Phone Number: What’s the Difference?
These three terms often get mixed up, but you should look at them separately when shopping.
| Plan type | Mobile data | US +1 number | Traditional voice and SMS |
|---|---|---|---|
| Data-only eSIM | Yes | Usually no | Usually no |
| US IP roaming eSIM | Yes | Not necessarily | Depends on the plan; often data-only |
| US native plan clearly listing a +1 number | Yes | Yes | Depends on the plan details and activation terms |
A US IP address is not a US phone number. When a website detects that your IP is in the US, that only reflects your internet exit point; it doesn’t automatically give you a +1 mobile number.
On the flip side, an eSIM with a +1 number doesn’t mean it will pass identity verification on every third-party platform. Banks, Uber, Yelp, and other websites may each have their own restrictions on short codes, number origin, or fraud screening.
7. How to Choose a JEKO US eSIM: Sightseeing vs. Needing a Phone Number
If you’re just doing a regular independent trip to New York, Los Angeles, or San Francisco, and you mostly use maps, Uber, LINE, social media, and email, start by comparing data-only eSIMs by number of days, data allowance, and partner carrier.
But if you need a real US phone number, take a look at the JEKO AT&T US Native Number eSIM.
According to JEKO’s current product page, some AT&T plans offer:
- A +1 US phone number.
- A native US IP and mobile data in covered areas.
- Calling and texting within the US, Canada, and Mexico as specified by the plan.
- Specific activation dates, phone compatibility requirements, and hotspot limits.
Before you buy, pay close attention: some plans need to be scheduled for activation in advance, with activation times handled in US Pacific Time (PT); your device must be unlocked and support the required eSIM and network specs. The product also has its own restrictions on Android, hotspot use, and returns/exchanges.
Important: having a +1 phone number doesn’t guarantee you’ll receive OTPs from OpenTable, Yelp, Uber, or every bank.

8. How to Set Up Dual SIM on iPhone: Keep Both Your Taiwan and US Numbers
If your phone supports dual SIM, you can usually assign different jobs to each line.
A common setup example:
- Go to Settings → Cellular and confirm your travel eSIM has been added.
- Set “Cellular Data” to your US eSIM.
- Keep your Taiwan line turned on for calls or SMS tied to your original number.
- If you have a +1 US number, choose which line to use for calls or texts as needed.
- Check “Allow Cellular Data Switching” and data roaming for each line so you don’t accidentally use your Taiwan number for data.
Note that an iPhone uses only one primary cellular data network at a time, and having two SIMs active doesn’t mean both can roam for free. Actual features depend on your phone, iOS version, and carrier support.

9. Run Through This Communication Checklist Before Your US Trip
- Your Uber account and phone verification are completed while you’re still in Taiwan.
- You can log in to your bank and credit card apps normally, and use app push verification if needed.
- For important restaurant bookings, you’ve saved the confirmation email, date, and party size.
- If you’ll use Yelp Waitlist, you know how you’ll receive notifications and what to do without SMS.
- If you need businesses to call you back, confirm that you’ve bought an eSIM that really includes a +1 number.
- Check the international roaming, SMS, and calling charges for your original Taiwan number.
- Make sure your phone supports eSIM and doesn’t have an incompatible carrier lock.
- After you land in the US, test your data connection and any voice/SMS features you need.
US eSIM, Calls, and Restaurant Reservations FAQ
Do I have to buy an eSIM with a phone number for a US trip?
Not necessarily. For general sightseeing, navigation, Uber, and internet-based messaging, a data-only eSIM may be enough. If you need local SMS waitlist notifications or businesses to call you back, then compare plans with a +1 number.
Do I need a US +1 cell number to book restaurants on OpenTable?
Not necessarily. OpenTable uses several channels, including email, app notifications, and SMS, and the actual requirements depend on the restaurant and account verification. If the form won’t accept an international number, ask the restaurant about alternatives.
Can I use Yelp Waitlist without a US number?
It depends on which contact methods the restaurant and platform accept. Yelp’s official waitlist process sends text messages, so if your +886 number can’t receive them, ask the host whether they can call your name on-site or use another method.
Do I have to re-verify my phone number for Uber in the US?
You don’t need to re-verify for every ride. But signing up for the first time, changing your number, or certain account security situations may require SMS, so it’s best to finish setting things up while you’re still in Taiwan.
Can I still use LINE and WhatsApp with just a data-only eSIM?
Yes. Both send messages and make calls over any available internet connection, so you don’t need a new US phone number. However, changing your account or reinstalling the app may trigger verification on your existing number.
Can a US +1 phone number receive Taiwanese bank OTPs?
It can’t directly replace the Taiwan number already linked to your account. If your bank sends verification messages to +886, you’ll still need to receive them on your original number or through another verification method the bank offers.
Is an AT&T US native eSIM guaranteed to receive verification codes from every platform?
No guarantee. Even if the plan supports traditional SMS, third-party platforms’ short code and fraud-screening rules can still keep some messages from getting through.
What should I do if a restaurant asks for my phone number but I only have a data-only eSIM?
First ask whether they accept a Taiwan international number, email, in-app messaging, or calling your name on-site. Don’t give a random US number that you can’t answer.
Think About How You’ll Use It First, Then Decide Whether You Need a +1 US Number
On your first independent trip to the US, you don’t need to assume you have to buy the most expensive native number plan just because you saw “receives OTPs.”
If you’ll mainly be navigating, ordering rides, chatting, and making regular restaurant bookings, a data-only eSIM plus keeping your Taiwan number is usually worth comparing first.
If you’ll often be waitlisting at popular restaurants, need to receive local texts, or want businesses to be able to call you directly, go for a plan that clearly lists a +1 phone number along with calling and SMS features.
Whichever you choose, finishing your Uber verification, confirming a backup for bank OTPs, and saving your restaurant booking emails before you leave will give you much more peace of mind than figuring out phone numbers after you land.
