TM SIM Registration for New vs Old Phones: A Comparison

If you’re registering your TM SIM, you might wonder whether the process is the same for new phones and old phones. The answer is mostly yes, but there are a few important differences and things to watch out for. I’ll break it down like I’m talking to a friend, clear and easy, with helpful tips so you don’t get stuck.

What’s the Same for Both New and Old Phones

Whether your phone is brand‑new or a few years old, the basic SIM registration steps are the same:

You enter your mobile number
You type your personal details
You upload a valid ID
You take a selfie for verification
You enter the OTP (One‑Time PIN) you receive

Both new and old phones need these steps because the SIM registration law requires identity verification linked to your mobile number.You can also read:Can Foreign Tourists Register TM SIM Without Address?

Where New and Old Phones Can Be Different

Here’s where things can vary when you register a TM SIM:

1. Network Recognition

Most new phones easily register with the TM network because they support the latest mobile standards and settings.
Some older phones may take a moment to connect properly before the system can send OTP or verify the SIM. You may need to reboot the phone or switch airplane mode on and off to refresh the network connection.

Dual‑SIM Phones

If you have a phone with two SIM slots:

Make sure your TM SIM is in the primary slot when you register online

Some older dual‑SIM phones don’t clearly show which SIM is active for messages, so you might miss the OTP

Newer phones usually show SIM icons right away, so you can easily see which one is receiving messages.

eSIM vs Physical SIM

Newer phones sometimes use eSIMs instead of physical SIM cards.

An eSIM registration process might look slightly different, but you still need to follow the same identity and OTP steps.
On older phones, you will likely use a physical SIM card, and registration works through regular SMS.

Even though the medium (eSIM or physical) is different, the registration steps remain generally the same.

Software Compatibility

Older phones may have older apps or older system software, which can sometimes make the GlobeOne app or online forms behave a bit differently.
In those cases, using a computer or another device to do the registration can help.

Receiving OTP

Both new and old phones rely on SMS to receive the OTP, but:

New phones often have fewer message glitches

Some older phones may have a full inbox, blocking new SMS including your OTP

Clearing message space first is a good idea if your phone feels slow or full.

Tips for a Smooth Registration on Any Phone

Whether your phone is new or old, here are easy tips to make registration smooth:

Check your signal before starting
Use stable internet (Wi‑Fi or good mobile data)
Put TM SIM in the main SIM slot so the phone gets the OTP
Clear old SMS so your inbox can receive the OTP
Take clear photos of your ID and selfie
If online registration fails, try the app or a store visit

FAQ’s

Yes. As long as the SIM is properly registered, your phone will send and receive calls, texts, and data normally.

No. The steps are the same. Just make sure you follow the prompts correctly.

Try restarting your phone, checking the SIM slot, clearing SMS, or switching to another device to request the OTP.

Not really. You just follow the same steps in your phone’s eSIM settings or the app.

Try taking the SIM out and reinserting it. If problems continue, visit a TM or Globe store for assistance.

Final Words

Most of the time, TM SIM registration works the same no matter whether your phone is old or new. The key things are network connection, OTP delivery, and correct details. Older phones may have small quirks like full inbox or SIM slot settings, but with a few easy steps, you’ll get your SIM registered and working.
