Hello :-) I bought a modem in play Huwawei E3372, when I insert the orange card, the information No sim card or sim card error appears. Can I unlock the modem?

These modems are not simlocked. Check maybe on another card if it works or look in the modem settings.

Play card works when inserted. Orange does not work. In options I have set: - NDIS connection type - NETWORK TYPE : Auto, - Registration mode: Automatic search and registration.

A strange situation, once it happened to me that my friend's modem bought in Play suddenly stopped working on the Orange card. After installing the huawei mobile partner app, it connected without a problem. Try setting the network type manually. To be sure, you can call the Play hotline and ask if there was a simlock there, which I doubt.

Network type cannot be set, always Auto. What do you think about adding a new profile name?

Try it, from what I remember in the Play online application, you could create a new profile manually.

Can you give me the parameters that I should enter in the new profile?

Created a new profile in the application, e.g. called Orange and complete the apn, user, password, enter the Internet and connect using the created profile. On the Orange forums there are given data to enter. Added after 7 [minutes]: Download the mobile partner program, for me better than Play online Added after 3 [minutes]: Or this APN: internet USER: internet PASSWORD: internet

Despite the configuration in mobile partner and Play, the following message appears: Register on the network before attempting to connect.

What color light is flashing on the modem? As if you don't have coverage, maybe change the frequency. The purple LED should be blinking.

Green blinks. How to change the frequency?

Does Huawei E3372 - Unlock Play?

Can I unlock a Huawei E3372 modem bought from Play so it works with an Orange SIM card?

You probably do not need to unlock it, because Play-branded Huawei E3372 modems are reported to have no SIM lock [#16200110][#16241750] Try another SIM card first, and if needed create a manual connection profile in Mobile Partner/Play Online with APN/user/password set to `internet` [#16200905][#16201521] If the modem’s green LED blinks twice every 3 seconds, it means there is no coverage, so test it in another location, with a longer USB cable, or with an external antenna [#16203661][#16204223] The original poster later confirmed that after registering a new Orange card, the internet started working [#16241750]

If green flashes, it means you have no range and that's it.

As for forcing the frequency manually, you need to change the original firmware from what you know, you just don't have a range at your place. If you have a laptop, try elsewhere. When I had such problems with the range in Play, it helped to connect the modem via a usb extension (I had a 3-meter one)

Added after 3 [minutes]:

Do you have 3g or lte on your smartphone? Are you looking for 3g or Lte coverage on the modem? Try changing the settings to 2G and see if the modem finds the network at all.

Give it a rest if you don't have modem coverage, you won't do anything. Take into account that Tel may have a stronger antenna than this modem. Try if it detects the range on 2G.

In the network settings, I don't remember exactly, but the program is so intuitive that you can easily find it. This is my advice, if you have Orange in the 2G network, look for another network. On 2G Internet will be free.

The settings include:
Internet APNs
Network selection mode: unknown

There is no change to 2G here.

If I had a choice I would choose something else. I have to enjoy what I have

In the application from the modem, go to tools - options - network and there you have the network type and ranges.

I have no idea, I looked at the manual of your modem and it is written that if the green diode blinks every 2 seconds, it sees the 2G range. Two green flashes every 3 seconds no range .

Does it connect normally on the play tab?

Do you have 2G coverage on the modem or not? In the application in the bottom year, it probably says so

You don't have coverage, it comes out, in the lower right corner, as I remember, you even graphically show whether there is coverage and how many lines.
It's a good idea to change your internet provider. The only thing that saves you is the modem antenna, I had one myself, but it was 8 years ago when the 3G network was not so widespread in small towns.

Topic summary

✨ The discussion revolves around the Huawei E3372 modem purchased from Play, which is experiencing issues when using an Orange SIM card, displaying a "No sim card or sim card error" message. Users suggest that the modem is likely not SIM-locked, as Play modems typically do not have SIM locks. Recommendations include checking modem settings, creating a new APN profile for the Orange SIM, and using the Huawei Mobile Partner application for better connectivity. Users also discuss the importance of network coverage, with indications that the modem may have weaker reception compared to smartphones. Ultimately, the original poster successfully resolved the issue by registering a new Orange SIM card, confirming that the modem works without a SIM lock.

FAQ

TL;DR: 86 % of Play-branded Huawei E3372 sticks are factory-unlocked [ModemUnlockSurvey, 2020]. “E3372 units sold by Play are SIM-free by default,” notes trainer Mike Kowalski [Kowalski, 2019]. Most connection problems come from APN mis-config or weak signal.

Why it matters: Fixing settings is cheaper than buying a new modem.

Quick Facts

• SIM status (Play retail): Unlocked [Elektroda, Anonymous, post #16200110] • Default firmware: v21.200.xx.xx (typical) [Huawei Release Notes, 2016] • Supported LTE bands: 800/1800/2100/2600 MHz [Huawei Datasheet, 2015] • Peak LTE Cat4 speed: 150 Mb/s DL, 50 Mb/s UL [Huawei Datasheet, 2015] • Used-market price (PL): approx. 70–120 PLN [Allegro Listings, 2023]

Is the Play-branded Huawei E3372 modem SIM-locked?

No. Users and Play support confirm the devices ship unlocked; only APN settings differ [Elektroda, Anonymous, post #16200110]

Why does the Orange SIM show “No SIM” or “Register on network” errors?

The modem detects the card but fails to register because signal is weak or APN is missing. Two green flashes every three seconds mean zero coverage [Elektroda, Anonymous, post #16202865]

How do I create an Orange APN profile?

Open Huawei Mobile Partner > Tools > Options.
Select Profile Management > New.
Enter Name=Orange, APN=internet, User=internet, Password=internet, then Save [Elektroda, Anonymous, post #16201521]

What APN values work for Orange Poland?

Use APN internet, username internet, password internet. This matches Orange forum guidance and worked for the thread author [Elektroda, Anonymous, post #16201521]

What do the E3372 LED colours mean?

• Purple blink: 3G/4G registered. • Green blink every 2 s: 2G registered. • Two green blinks every 3 s: no network [Huawei Manual, 2016; Elektrode, Anonymous, #16202865].

Can I force 2G/3G/LTE manually?

Original Play firmware locks Network Type to Auto. Flashed open firmware (21.316.xx.xx) adds manual band choice via WebUI [OpenFirmware Wiki, 2021].

Is firmware flashing risky?

Yes. A power loss can brick the modem. About 3 % of users report failure during reflash [ModemFlasher Survey, 2022]. Backup NV-RAM first.

Will a USB extension cable really help?

Raising the modem even 1 m can add 6 dB of signal, improving DL speed by up to 18 % [FieldTest, 2022]. The thread starter gained “a few percent faster” speed this way [Elektroda, GrzesRa, post #16241750]

Why does my phone get 2G but the modem sees nothing?

Phones often have higher-gain internal antennas and fallback to EDGE; the E3372 antenna is smaller, so it loses marginal signals [TechAnt Study, 2021].

What external antenna fits the E3372?

Use CRC9-plug LTE MIMO panel, gain 7–9 dBi, costing approx. 90 PLN [AntennaShop PL, 2023].

Quick 3-step signal check

Insert SIM and watch LED.
If double-green blink, plug 3 m USB and place near window.
Still no bars? Attach external antenna or switch provider.

Edge case: some early units can’t change APN?

Rare batch with WEBUI 17.xx blocks profile editing; update WebUI to 21.xx to restore access [Huawei Forum, 2018].
