Adapter for two SIM-cards, the continuation of a conversation
It seems unremarkable little article on Mobile-Review has caused a storm of responses concerned citizens subscribers. Letters and questions so much, that answer each wrote is physically impossible. Hence the return to the topic, but comprehensive recommendations to still not work. The most characteristic and frequently asked questions have been systematized, try to give them more or less complete answers.
Commercial delivery - it's not for us
We got a lot of "official inquiries" from all regions of Russia in the mass / wholesale those "dvuhsimochnyh" adapters, including even with the above bank information. Thank you for your confidence in our resources, but the wholesale and retail sales of equipment we do not do - not the profile. There are many suppliers, and they certainly can help. Can not advertise a particular company, but even the most primitive search in Yandex will take you at least two or three companies who have coveted the adapter in the retail and wholesale options for delivery.
The issue price for these few months is still open - at the Moscow radio markets 450-600 rub. Retail is still asking and receiving. MegaFon Moscow offices sell adapters for $ 11.80 (c taxes), but it is now selling them in there and when / if we will not know. Maybe in a few days still appear, otherwise it would be stupid of MegaFon. Prices from online stores has stabilized at $ 18-20, which roughly corresponds to a price on a special battery cover with adapters for 2 SIM-cards. Is also natural: the demand for such solutions is stable, and retail prices should remain comparable, regardless of prices in the wholesale supply options. Electrical circuit device, we also do not have, respectively, and send it can not.
Small technical tricks
The compatibility of the adapter with different phone models was not easy, unequivocal advice to not venture. For example, I never managed to make this device work with a single instance Siemens Me45, although I know: many people have this adapter with Siemens 45-series works just fine. The same applies to the phones Motorola: performance with many of the model is confirmed, but not everyone can get an adapter to work. On phones such as Noki and no problems noted, however, a couple of angry letters in the box are. It seems that in most cases the "incompatibility" to blame ourselves. Let's try to mention at least the most common mistakes.
Cut right
Advice on the use of a sharp knife to cut the SIM-card was not entirely successful. Yes, you can use a knife, but to begin cutting the card from the copper contacts is not recommended - is fraught. Hand shaking and almost invariably a thin copper strip comes off as a result of SIM-card is in the bin. If we are cut with a knife, then cut from the plastic / cardboard, and try to avoid whipping blade tool.But the "consistently excellent result" obtained by use of scissors for metal, even better - use sharp cutter.
Alcohol - around the head
The area of contact points in the compartment adapter is smaller than that in standard card connection, and the adapter contacts are spring loaded. And therefore a good electrical contact is especially important. Pelt / Needle file is not suitable, since srezhut thin layer of processed brass, and the phone a week or two will hang unpredictably and require "insert the SIM-card!". Before the final assembly of the adapter should carefully wash the surface with alcohol cutoff cards and "hemp" contacts inside the adapter. Any methanol-containing mixtures reject with indignation: the nearest pharmacy may be for 10-15 rubles. acquire the required bubble liquid. In the name of peace monitoring bodies rodnenky ethanol could be "ethanol solution for external use only" or something else - it does not matter. The main thing is that the numbers match (about 95%), and - heaven forbid! - No muddy additives such as "tincture of hawthorn.
Dimensions are important
Last time, we specifically pointed out the importance of adhering to size - "cut" SIM-card must be strictly for a pattern from a kit. We repeat: it is too short "stub" can not make money, and if it will work, the future certainly encounter problems when trying to restore the form factor of a standard card. The set includes a plastic piece, "emulators", but trimmed SIM-card is better in this plastic box not much to hang out. Do not forget the outside of the plastic "emulator" stick a thick layer (several layers) adhesive tape - included with the adapter blank tapes are not suitable. Spring contacts compartments SIM-cards of most phones is inevitable "pushed" SIM-card from the plastic template on the millimeter or so up the contact will deteriorate and you will long to find the cause of the periodic glitches in the phone. The kit includes an adapter pad-padding: strongly recommend its use in cases where the holder of SIM-card phone made in the form of side rails and pushes the top card.
Reported problems and features
There are complaints about the reduction of working hours in standby mode. Probable cause - consumption chip that controls switching between SIM-cards. Unpleasant for those who use the phone very rarely as "emergency" means of communication. In normal operation the minimum additional power is unlikely to significantly affect the time of the phone on one battery charge. Occur during the rapid freezing apparatus switching the phone off immediately after the registration of the network: it is better to wait at least a minute. Provided in a number of smart mode "in an airplane (complete shutdown the radio unit) SIM-card does not switch, the machine should shut down completely. Learn how SIM-card is connected while roaming the easiest going to the SIM-menu for different operators, it is different. Another convenient option - to leave the input pin-code on only one of two SIM-cards. And once again: we have not tested the adapter with a lot of phones, the device you purchase at your own risk, and return it to the seller will not succeed. But from reviews in the forums, in most cases the device is working properly. We hope that the topic Dual Sim Adaptor higher return is not necessary.
